Overview of the changes:
- ARM support: separate ext2 /boot, no LILO
- avoid race condition with devmapper
- trap ERR so that -e in shebang doesn't result in extra cleanup hassle
- configurable root filesystem type (ext4 by default)
- jumps through parted hoops
Details:
1. LILO is x86-specific while the rest of the script can be used
to prepare e.g. Marvell ArmadaXP or CuBox images; we can generally
count on uboot supporting ext2 for relatively sane platforms but
not ext4 that would be a better root filesystem performance-wise.
2. Apparently /dev/mapper/loopXpY can be still missing at the time
when kpartx returns and pop up a bit later... sit there, wait
and check for it.
3. If something went wrong with any command of the script it would bail out
due to -e in shebang; it is now better to clean up the loopback device
and its mappings in this situation either.
4. One size doesn't fit all, really.
5. The parted sizing was sloppy as in broken, now it's just half insane.
Someone's decision to stick units and auto-alignment knobs into
a single one was apparently hilarious...
http://www.gnu.org/software/parted/manual/parted.html#unit
Manual loop/dm cleanup is described in documentation just in case.
/boot size meter is suboptimal in terms of additional I/O incurred,
will be most likely rewritten to make use of advance "du -s".
Hardly belonged there in the first place and became a culprit
during armh branch development since it had to be forked in
an ugly manner; move to rootfs hooks and be done with it.
VM images will be able to benefit either *but* installed systems
might have some trouble when this is implemented:
http://lists.altlinux.org/pipermail/devel/2013-May/197447.html
Split off use/live/x11 as a common free/proprietary ground either
(this refactoring had to be performed in parallel with x11 feature
being revamped, diffs quickly became intertangled unfortunately).
This has had several goals:
- a target suitable for x86 and armh providing a rather
minimal set of base xorg packages and generic drivers;
- task-oriented targets for graphics use cases:
+ "desktop" means rather 2D focus with 3D being welcome
or even essential but not performance critical, thus
"a slower driver is fine as long as it does work";
+ "3d" means specific 3D performance being critical,
that is "no 3D means no use at all".
Regarding the free and proprietary 3D-capable drivers:
the previous idea was to split out some common ground
and then add the contenders on top of that; the current
approach is based on the observation that the live images
requiring proprietary NVIDIA/AMD drivers *by default*
are usually of not much use with hardware that lacks
proper 3D acceleration (like Tseng cards) or the driver
support for that (like Matrox these days).
Intel videodriver makes for a special case though:
it is both free and top-notch performer.
Thanks sem@ and boyarsh@ for discussion.
PS: xorg-drv-{keyboard,mouse,void} dropped;
those who need these can usually help themselves.
These handle only VE-like products (think TWRP on Nexus 7);
the proper image support should be backported later on.
An experiment in layered configurations is still in its
early stages regarding ARM zoo...
The feature officially introduces the "engineering passwords"
including empty ones which have been around since forever but
weren't properly managed (and still are not, at least until
there are no stray passwd/chpasswd/usermod calls in both the
profile, installer-features and all the other related parts).
It is based on an m-p-d init3-users script by stanv@ but was
cleaned up and restructured in a pretty severe manner; thanks
glebfm@ for additional discussion.
This also cleans up the kludge previously stuck into build-vm.
Note that vm/icewm sports graphical autologin now as well as
the default root password (which can be overridden by passing
ROOTPW=... to make but it is a change from the previous state
of affairs indeed).
The issue is that use/fonts/infinality doesn't actually
require the script hook thus registering the feature's
name in FEATURES variable so that the feature's contents
get copied over is not neccessary (distcfg.mk build-up
will have happened anyways).
But that's confusing if one's forgot this peculiarity
(like me today) or never knew of it, so let's spare
some frustration.
This feature is more generally applicable indeed;
might result in duplication due to the installer
components adding "efivars" independently but that
is to be sorted out later in those components:
- check whether it's added already sometime soon;
- maybe stop adding that at some point in the future.
install2 and rescue roots still need this too though.
Classic VEs don't carry any kernel since these are running
under a single OpenVZ (or potentially LXC) kernel image;
ARM Multiboot (TWRP in this particular case) allows to boot
off a chroot via kexec, and we need a kernel in it for that,
obviously.
No bootloader required inside such VE though.
This subprofile is akin to THE_* variables family: the configuration
bits and script hooks sitting there influence whatever chroot is
declared to be the user facing one in the end, whether it comes
from vm image or live subprofile.
The services feature ought to be a changeset of its own which would
be based on rootfs and become the base for ve/vm changes but I chose
to just do it atomically; some pre-existing duplicates are pruned now.
INSTALL2_PACKAGES turned out to be sensitive to the
feature addition order: if efi was added before install2
then the packages added by the former were overridden
by the latter.
This is also related to commit g7b76c73 as +installer
can be added pretty much anywhere, there's no warranty
that use/install2 appears early enough in configuration
build-up sequence.
This one is a part of a larger rewrite to move away from
distro-centric build-up to configuration-centric one with
the particular packaging being of secondary importance
compared to actual functionality.
Another service that's not very useful on a LiveCD;
maybe should be enabled by default upon installation,
this also requires a proper framework in place.
This reverts commit ae44169139
as libglx has been fixed already; see #27340 and #28782 for
the details, huge thanks go to Alexey Borisenkov for his
thorough investigation and patches as well as to shrek@
and sin@ for their cooperation to get this fixed in Sisyphus.
Moved the packages which impeded pkglist reuse for live distros
so that these stay within dedicated rescue images but don't
neccessarily go into the more generic ones where things like
fdisk are still quite useful.
This is to cope with #28782 while the culprit is being found out;
not much of a loss while #27340 is open (thus no 3D with vboxdrv
anyways).
I chose to avoid pulling the service related machinery into
vmguest (and haven't got around to factoring it out from live
feature's scripts into a standalone form) so had to tweak these
as well.
The expected behaviour is to have online repositories enabled
when the livecd is running; the trouble with runtime detection
relates to the asynchronous nature of network configuration,
connection might get probed just before it is brought up
(thus failing the test).
Systems having been installed-from-live don't misbehave this way
so left unmolested.
Runtime detection is still available via use/live/repo/online
but is definitely not the default mechanism.
The former helps totem a lot regarding actual video reproduction,
suggested for gnome3-default metapackage; the latter helps aris@
to actually get any sound out, so is supposed to land there too.
There's a need for a separate boot target since
persistent storage is way slower than tmpfs indeed;
usbflash has a tendency for huge performance drops
given simultaneous writes in addition to reads which
are the bottleneck already.
make-initrd-propagator 0.18 introduced ext4 rw slice,
so the corresponding kernel module needs to be included
into stage1; see also #28289.
NB: not available on x86_64-efi (or hybrid GPT to be strict)
due to fragility of the hack being made: parted(8) panics
upon seeing that, and good ol' fdisk is unable to treat it.
NB: use/live/rw use/rescue/rx use/syslinux/ui/gfxboot
are unlikely to play very nice together due to the latter's
magic l10n: "session" label is taken by live_rw config snippet
and *is* translated in design-bootloader-source;
OTOH "rescue_session" is *not*.
The original mkisofs would only care for the proper ISO9660 image
but we've switched to xorriso which is able to perform the hack
to yield UEFI hybrid images; thus no need for the postprocessing.
Requires mkimage >= 0.2.5 and xorriso (obviously).
Please see the bug for explanations; too bad I chose to limit this
workaround to experimental gnustep image yesterday when aen@ suggested
to apply it universally...
The reason is to contain the implementation details
within this feature while adding the ability to include
everything it can provide (e.g., for rescue images).
This includes an updated version of 50-fontconfig script
which actually works (the preliminary one attached to #28612
didn't); thanks zerg@ and cow@ for providing the incentive
to introduce it.
Based on m-p-d and installer-feature-kdesktop-fontconfig.
It's possible that use/efi/signed target has fired already
at the time when use/efi/shell is invoked; shouldn't clobber
the signed shell with unsigned one.
The various *8168 and friends among kernel modules
have finally been pushed into a designated target
so that RM doesn't have to care which particular
additional ethernet modules are available in this
particular branch and kernel.
Tweak distros as appropriate.
NB: *maybe* this is required by distro/.base either.
acpi_call is used far too often when dealing with the newer
portable x86 hardware, we're better off including it when
it's available.
regular.mk adjusted appropriately.
Richard and Theo would probably roll their eyes at this point
but the unfortunate reality is that wireless hardware is very
much dependent on firmware being explicitly provided; so here
it is.
rtl8192 kernel module added since it's present in t6/branch
at least.
It was removing autodetection setting completely
thus implicitly setting it to the default "all"
with make-initrd-0.8.1+; just set it to be empty.
Thanks legion@ and boyarsh@; see also #28578.
It'd be better for this commit to appear before 0.9.7
(and clobber the original one) but at least the added
functionality has been tested; time to generalize it.
The issue has shown up in regular-*-20130207: /etc/resolv.conf
would suddenly be empty upon successful bootup in virtualbox
with a single DHCP configurable ethernet.
dmesg has some trouble signs:
aufs au_lkup_neg:267:kworker/0:2[998]:
I/O Error, resolv.conf should be negative on b0
sem@ tells something like that has been seen before in a different
configuration (multiple aufs overlays with /etc/ and /var sitting
in different ones resulting in broken hardlinks); rescue boot with
a test "echo > /etc/resolv.conf" yields an I/O error either.
The patch is loosely based upon livecd-net-eth and
m-p-d::profiles/live/image-scripts.d/init3-{network,resolve}.
See also #28484 for the (still ongoing) discussion.
Once upon a time the first and only ethernet interface
on a Linux system used to be known under the name of eth0;
but years passed and the systemd shadow has drawn closer
even to the seemingly remote areas like interface names.
In short, it might get named e.g. enp0s3 (a more human
friendly name of course) and the exact name is to be
figured out in runtime as well.
Sigh.
The issue is that gfxboot's gettext support works on "label"
strings but doesn't work properly on "menu label" ones as of 4.04
(the "menu label" translations pop up in the "Loading ..." window
but menu items themselves are unaffected thus untranslated).
NB: debian wheezy's syslinux-4.05 package patchset contains
somewhat related 07-gfxboot-menu-label.patch; might be worth
attention given that debian folks participate in upstream.
It appeared that plymouthd.conf wasn't set up properly
thus "service plymouth stop" didn't result in anything
meaningful; thanks boyarsh@ for his help figuring this
out again.
Its support was dropped in mkimage some time ago
since xorriso semantics changed quite considerably
and the tweak that was done here is now performed
out-of-box thus no longer needed.
It's aimed at providing UEFI shell implementation which is very
useful for repairs and debug; if the "signed" mode is requested
then the signed variant is used either.
Please note that there are two distinct uses:
- a shell lying around on a filesystem to be copied by hand;
- a shell available in EFI part of boot media to be launched
by firmware's or standalone boot manager (e.g. refind).
The reason is that the most interesting live images by now are
installable ones, and while configurable boot order is not there yet
the "classic" livecd images will require manual choice to boot.
Thanks sem@ for reminding of that FR (which is still open).
Currently done for 40-autologin script only but might be
more widely useful: when describing an action to be done
while forming the LiveCD image, also prepare the one that
undoes the effect so that an installed LiveCD doesn't
(mis)behave as if it were young again.
NB: livecd-install provides 50-{gdm,kdm}-autologin-off.sh
hooks which can collide with ours, so let's override those
until things are sorted out properly at both sides.
PS: some half-year old nodm hacks are still in place for t6/branch
(and #27451 should be re-examined when dropping those).
- added destination homeros-nano.iso yields minimal
speaking image;
- added "homeros" feature contain scripts appropriate
for general Homeros functions but need further development.
It's not e17-default alone right now, gnome-icon-theme package
appears requisite at the moment so that menus and IBar aren't
half-empty regarding graphics.
Thanks aris@ for the advice and lots of patience with me.
It's a separate installation step to set the LUKS password;
see also #28200 for (terse) discussion and instructions on
getting this actually working for a distro.
There's use/x11/kde already but that serves somewhat different
purpose as of today; the naming issue (kde vs kde4) was tersely
discussed with sin@ at the time of the merge of his KDE4 image
related bits and it's still not that clear.
Let's try this way and see if existing images would be ported
to use/x11/kde4.
There's a possibility to run into IA32 EFI but that's rather
uninteresting hardware (ancient Xeon servers and <s>outdated</s>
early Intel Mac laptops). Just drop it on the floor.
As x86_64 UEFI support would result in "2D hybrid(r)(tm)" image
which boots with all combinations of BIOS/UEFI by CD|DVD/Flash
(or at least should boot), some downgrace seems due: use/efi will
turn use/isohybrid on non-x86_64 -- which will require further
tweaks on PPC/ARM some day.
The initial approach required some quite involved postprocessing
as described in http://www.altlinux.org/UEFI#HOWTO; after having
ironed out the kinks so that initial EFI support could be merged
into mkimage proper we're better off just using it, eh?
The previous part was fixed and discussed in commit
c30490e2e884f8655a2704fa6a84e60b13876874;
so much for a deduplication effort...
This would result in almost immediate
make[1]: *** [profile/populate] Error 2
as well.
propagator-20121109-alt1 obsoleted initfs (and dropped
mkinitfs script altogether); that was taken into account
in both make-initrd-propagator and mkimage-profiles-desktop
but not in mkimage proper, see also discussion in #27976.
EFI/UEFI is mostly about partitioning and bootloader setup,
at least from a distribution's point of view; so the
appropriate tools should be handy and firmware interface
module should not be exterminated from installer images
but get autoloaded instead.
Please note that while there exists 32-bit x86 EFI
we don't bother with it at the time being: it's relevant
to some irrelevant Xeon systems as well as for the older
Intel Macs (<2008) that are long out of fashion anyways.
That is, initially we deal with x86_64 EFI only.
This was requested by aris@ for live-gnome.iso but is so far
reasonable enough to do by default: the case of a LiveCD
including X and a display manager but willing to get on
with startx by default is rather nonexistant by now.
*Of course* the "weird" [ ... ] || ... construct meant to avoid
the non-zero exit status of the whole thing wasn't employed
where it actually does make the difference!
Thanks ildar@ for hitting and reporting this, as in
+ verbose '/usr/lib64/propagator exists'
+ '[' -n '' ']'
mki-scripts: .../stage1/scripts.d/80-make-initfs: unable to run script.
make[3]: *** [run-scripts] Error 1
This is thanks to the fact that alterator-based install2 needs
alterator-browser-qt which needs X11 which needs working device drivers
-- and at least AMD C60 APU would only yield a nice dotted white screen
without that firmware.
Roughly the same for X11 bearing LiveCD images.
The issue that appeared pretty hard to diagnose occured
to be the enhancement made in make-initrd-propagator=0.8.1-alt1.2
(that didn't hit Sisyphus until merged into 0.10-alt1) which
drops propagator dependency.
And that was optimized out in m-p, of course.
The added pdir check was a hillarious(tm) overlooked bug indeed:
I tried to put .../initfs/initfs instead of .../initfs as the result.
Duly spotted by torabora@, thanks a lot.
Still the kmod+propagator+kernel-image combo needed some tweaking too,
see #27640
It's pretty ugly but dropping the current way
means losing the dependency tracking which is
critical to get the required alterator module
into install2.
Thanks mithraen@ for spotting, boyarsh@ for explaining,
and legion@ for hearty support :)
The problem would manifest itself like this:
/.host/script.sh: line 20: /usr/lib64/propagator/initfs: \
No such file or directory
mki-scripts: .../stage1/scripts.d/80-make-initfs: unable to run script.
Thanks Serg Markov for bringing my attention to this:
http://www.opennet.ru/openforum/vsluhforumID3/86552.html#61
While the official distros might skip some filesystems for
support reasons there's no reason for community distros to
do so either.
Let's try that with icewm.iso...
NB: installer has a misfeature of dropping jfs/reiserfs
support in runtime unless "expertmode" magic word
is on the kernel bootargs string (#27763, #17368).
Its immediate purpose was influencing the GRUB boot menu
*but* the implemented mechanism is actually a part of the
long planned text branding and might be further merged
into branding when hierarchical features finally chime in.
So let's get the naming straight before it breeds.
See http://www.opennet.ru/openforum/vsluhforumID3/86239.html#1
for a query that has led to this one; in particular,
- xdm dropped (won't log in root and there are no users yet);
- network is brought up and configured via DHCP by default;
- apt-get works out-of-box;
- default image size is twice the chroot size.
3.5.2-std-def-alt2 brings boot problems which were absent
with 3.4.x-std-def and are absent with 3.5.x-un-def;
seems like it's better to stay with known good variant
at the moment instead of having to fall back to it.
The missing "; @:" at the end of the otherwise recipeless rule
resulted in target graph being broken; I should have checked this
when introducing these aliases (the intent was to reduce noise).
Thanks both drool@ for his mild frustration with the current
documentation as well as Greg Kroah-Hartman, Heikki Orsila
and Neil Brown for http://lwn.net/Articles/504814/ -- the docs
should really emphasize *why* something is done, not *how*,
as the "how" part is better documented with the code itself
(that doesn't mean that "the big picture" isn't needed).
That sub/stage2/install2 was somewhat clumsy actually as it looked
like a hierarchical thing while being a substitution thing:
generic stage2 would get put in place renamed as install2.
This could only get worse with hierarchical features which have
already been both requested and considered for quite a time,
and "stage2 at install2" reads much more naturally.
There were heaps of "if type -t git" there already;
it wasn't an unintentional mishap but rather a moderate
copy-paste to get the use cases, and now these seem to
have essentially settled.
So time to scrap some dups.
NB: the scripts in the generated profile can't rely on
the contents of the metaprofile (these need to be able
to work in standalone case either), so a bit of crap
still lurks there.
Found myself pretty silly while sittin' at the rescue console
and bein' unable to leave the cool server room for a way
more comfortable armchair and a laptop's keyboard...
(yes, it was that disk array needing GPT tools)
This trots along the TODO item on text branding
and hopefully helps Michael Radyuk (torabora)
with his feature request to tweak the installer's
"Install ALT Linux" label; as an example, Simply
will now offer to "Install Simply Linux".
This one was suggested by enp@ for industrial use where
some extra protection for the boot process might be quite
desirable.
If no syslinux ui was specified (the stock configuration paths
ensure there is one) or if it was set to "none" explicitly,
then there's no boot: prompt (let alone any menu).
If there's a need to ensure that the boot process is not
interruptable by Ctrl/Shift/Caps Lock/Scroll Lock.
Also pulled the pkglist/kmodule part out of distro/server-mini's
recipe and started off a standalone feature based on it.
NB: el-smp kernel now contains aufs as a module but propagator
doesn't try to modprobe it.
TDE distros don't really need kdm4 which was proposed as
a replacement by zerg@ (for all the valid reasons but kdm3
wasn't maintained at that point, this has changed since).
The reason is that package lists and individual packages
are processed in different dependency resolution "transactions"
by mkimage; thus if packages (the more precise form of specifying
the contents) come first they can't override the lists appearing
later, and that's wrong: we should be able to specify the more
generic things and then pinpoint the specifics.
This became apparent while authoring [[Mkimage/Profiles/m-p/howto]]
asked for by drool@.
The problem was spotted by Alexander Bandura:
bin/tar2vm wasn't present in the generated profile.
I considered extending features.in/Makefile to include
bin/ alongside lib/ but that would make the helper's location
unpredictable (unless BUILDDIR is specified explicitly) so
restricting sudoers would be harder; worse yet, the copied file
would come with write access for the user building an image.
The implications in restricted case are complex enough anyways
so the recommended implementation would only include a fixed
readonly location like /usr/share/mkimage-profiles/bin/tar2vm
as laid out in doc/vm.txt, and that means it's in the metaprofile
not a generated profile.
mkimage implementation requires that the variables
to be passed to the scripts are to be prefixed with
GLOBAL_ or INFO_ tags as appropriate; in this case
the upstream makefile didn't care to.
It's better to rather just move the raw image instead
of specifically converting it into the same, and there's
no need for qemu-img altogether then.
Let's drop the intermediate raw image after successful
conversion as well.
Setup network settings:
1. Init /etc/hosts with "127.0.0.1 localhost"
2. Set hostname, domainname
3. Set defaults for NetworkManager or
attempt to autoconfigure eth0 by etcnet.
Based on init3-network script from m-p-d.
A virtual machine isn't very useful if there are no means
to access it; let's bring up the basic networking and provide
root SSH access via pre-existing public key.
As the remote access with known default credentials is roughly
equivalent to just lending one's VMs to anyone with network
access to it, the fallback root password is now exterminated;
you have to provide one (or a long enough random string
if you plan to use keys only, see e.g. apg utility).
It appears that reusing installer-feature-*-stage3 packages
is perfectly fine with VM images; these just need to be removed
after the package scripts they carry have worked out.
Raw disk images are convenient and universal
but there are custom formats like Qemu's qcow2
providing additional features, e.g. copy-on-write
or space savings. All of this ultimately belongs
to mkimage but in the mean time has been implemented
here as well.
Yes, mkimage-profiles is now able to build VM disk images.
So far the support is pretty basic:
- a single hard drive image with a single partition/FS
- only stock root password is configurable
- LILO is hardwired as a bootloader
The resulting images tend to boot under qemu/kvm though.
Please see doc/vm.txt for the warning regarding additional
privileges and setup required. This was started back in
February but I still hoped to avoid sudo/privileged helper
(and libguestfs is almost as undistributable as can be)...
Thanks:

- Alexey Morarash who reworked that as https://github.com/tuxofil/linsygen
- led@, legion@, vitty@, aen@ for providing advice and inspiration
This one is contributed by Max Kosmach and somewhat
streamlined/tweaked by me; a part of it rather belongs to
nodm and xinitrc packages but is not exactly trivial to get it
there due to the looming systemd-logind/consolekit disaster;
see also #27449.
Several hacks to make NetworkManager usable in a LiveCD environment
are there too (but it resists so far).
Why would anyone try to remove apt when it's needed
for package dependency tracking for the installation,
it only takes a less cursory look at the build.log
to figure out it didn't actually happen anyways...
An initial draft of it was done half a year ago but several tricky
thingies had kept the code from showing up as it was rather brittle
and incomplete.
This implementation involves quite a few changes all over the place
but finally works good enough for live and installer images.
Please pay attention to the versions of these packages:
- installer-feature-setup-plymouth (0.3.2-alt1+)
- branding-altlinux-sisyphus (20110706-alt2+ if used)
- plymouth (0.8.3-alt20.git20110406+)

Just like livecd-install, graphical installer KMS support
looks better as an optional part of install2 feature.
Of course it's optional only if the release manager is fine
with VESA drivers and not KMS-requiring intel/radeon/nouveau;
thanks led@ for a confirmation just in case.
After having added metadata dependency livecd-install
started to look more like a feature than like an intermediate
distribution target; so things were shuffled a bit that way.
This further refines the modular build by making
metadata being a clearly separated feature rather
than having to rely on runtime tests, and also by
moving the code which cares for kernel bits of base
installation (.base list) in a feature of its own.
There's more to it but let's get the ball rolling first.
The initial work covered live images but missed an installer bit
(thus notes and slideshow were missing in install2) while forgetting
to put branding packages into base list (thus kindly making these
available for *manual* installation sometime after, ouch).
NB: for the feature to work properly the chosen branding
package set should have proper Provides: and Conflicts:,
specifically it must explicitly conflict with the most
lexicographically cool package set around (these days
it's sisyphus-server-light).
As duly noted by glebfm@, branding issues need more attention
by now since only stage1/install2 got some of it so far in this
regard. Hence the dedicated feature comes to the rescue
(well no, it doesn't actually mess with rescue!).
use/slinux-live: in p6 slinux had install-dvd version too
lists/slinux/misc-dvd: user 3d-proprietary comes from use/x11/3d-proprietary
lists/slinux/misc-dvd:restore compiz
slinux: use/syslinux/localboot.cfg
This script specifies the (excessive) lists of services
to be enabled and disabled explicitly; these are mostly based
on profiles/live/image-scripts.d/init3-services from m-p-d.
There might be systemd related pecularities though...
There's no real reason to keep bcmwl and ndiswrapper
around exclusively as the currently available support
vastly takes over the early attempts at the task.
(it's not about bare firmware though, and some day
something like use/hardware/wireless should get in)
Initial SPICE support has been added for kvm/libvirt installation
and boot-up using qxl and spice by default as proposed by shaba@.
VirtualBox part is shifted a level deeper correspondingly
but otherwise stays the same.
It is actually an effort by glebfm@ to create an experimental
systemd-based Simply Linux LiveCD; I merely reviewed the original
diff, moved kernel related bits to firmware (see preceding commits)
and introduced a dedicated pkglist namespace by creating a directory.
THE_PACKAGES_REGEXP is in place, let's rebase firmware packages
so these would be available in LiveCDs either.
The news for systems being installed is that MAIN_* is optional
while THE_* is included in base system; firmware packages tend
to be pretty tiny and harmless.
kernel-wifi pkglist has absolutely no sense by now, hence purged;
firmware-rt* and firmware-i2400m are merged into firmware-linux.
There were STAGE1_PACKAGES_REGEXP and MAIN_PACKAGES_REGEXP
but adding more of those was postponed to avoid bloat and
bitrot; THE_PACKAGES_REGEXP is needed for use/firmware now
and looks like BASE_PACKAGES_REGEXP and LIVE_PACKAGES_REGEXP
will be useful before too long either.
Docs updated to include stage-specific package related vatiables.
Looks like the 128k default block size is pretty well chosen:
it saves ~6% of image size compared to 64k, and subsequent
differences are ~3% per doubling the block size up to 1M
(thanks led@ for carrying out the tests).
So we'll stick with 256k for "normal" xz compression (inodes
uncompressed) and get 512k back for "tight" one (compressed).
The runtime performance issues are to be examined yet when
bootchart or the like is deployed, nothing drastic though.
With "fast" (gzip/lzo) squash compression inodes go unmolested.
For the record, tight live-webkiosk builds as 95M image in 3:40,
and tight live-flightgear.iso builds as 669M image in 6:34. Nice.
There's no much sense going for 1M block size: e.g. live-webkiosk
would drop to 93M (3:46) but its load time would increase up to
2:07 as compared to 1:48 for -b 524288 and 1:42 for -b 262144 -noI
on a Duron 500/512M system given the very same DVD+RW media.
The existing implementation would handle kernel differences
just fine but a bit too automatically: if it sees xz support,
that's what will end up being used (and if there's -Xbcj binary
compression filter available for the target platform, it will
be applied unequivocally either).
It's perfectly suitabe for getting fine-tuned release images
but is also a bit too resource-consuming while developing the
image configuration which has no business with its compression.
The one and only knob is SQUASHFS (see doc/variables.txt);
to give an idea of the differences, here are some numbers
for a mostly-binary (43% as per 99-elf-stats) webkiosk livecd
and a rather less so (18%) flightgear one on a dual quad-core
X5570 node (each mksquashfs run used up all the cores):
SQUASHFS | live-webkiosk.iso | live-flightgear.iso
---------+-------------------+---------------------
fast | 3:30 / 130M | 5:11 / 852M
normal * | 3:37 / 100M | 5:35 / 688M
tight | 3:50 / 98M | 6:47 / 683M
Thus if the knob isn't fiddled with, the defaults will allow
for a reasonably fast build of a pretty slim image; if one is
building a release or if a particular image is very sensitive
being close to the media capacity then just add SQUASHFS=tight
and see it a percent or two down on size.
Please note that lzo/gzip-compressed images are also quicker
to uncompress thus further helping with test iterations.
Thanks to led@ and glebfm@ for helpful hints and questions.
APM enabled notebooks would usually hibernate to
a partition of special type and special format;
thus to make use of this APM BIOS feature folks
might need a corresponding formatter.
Thanks snejok@ for spotting the missing, I didn't get around
to tests with headphones...
Also fixed nouveau getting in after target shuffling,
and tweaked firefox homepage to be useful in this context.
- incompatible change (to fix the rather broken early style):
use/syslinux/ui-% is now use/syslinux/ui/%;
- default timeout changed to 9 seconds (long enough and keeps
the countdown in a single figure);
- added totaltimeout of 300 seconds;
- provided live kiosk images with almost-instant boot by default;
...and some other assorted tweaks here and there, sorry.
Thanks to a reviewer who came with useful feedback and a goal:
http://www.opennet.ru/openforum/vsluhforumID3/83728.html#136
the live-webkiosk image got forked into a separate one:
- dropped DRI, virtualbox GA, mc & co, docs, rpmdb;
- added Russian keyboard layout (ctrl+shift to toggle);
- rebased live-webkiosk onto live-webkiosk-mini ;-)
Maybe vbox guest additions will get back but rpmdb is a bit
impractical on a kiosk squashfs image, even in presence of
aufs rw overlay.
Now is the time for all fonts to be pulled in when needed and not
along with the X server and hardware drivers; tablet support is
moved to a (preexisting) specific target either.
There's no need now to arch-discriminate a few older drivers too.
There's much reason for reuse instead of duplication
among the different stage2-based subprofiles.
In particular, the rather monolithic driver cleanup script
of the ancient is better done in several clear pieces with
the final depmod run.
Scripts dropping apt/rpm databases will dump pkglist first.
A script purging /boot/* will honour live-install if present.
Minor inno^Wfixups all over the map too.
The previous configuration would result in intel-only
3D being available since nouveau and radeon kernel modules
are packaged separately with most kernel-images; getting
NVIDIA/AMD drivers in is more tricky due to availability
of both proprietary and free implementations with the choice
being rather a tradeoff in each case (somewhat less so with
ATI/AMD drivers).
So this is a first shot at the problem: FlightGear would
freeze on me with today's nouveau.
As was noted by Alexey Shabalin in libosinfo context,
current ALT Linux images tend to lack ISO9660 metadata
-- which they did have back in the day of Master 2.4.
Please note that the data collection occurs this way
due to mkimage's config.mk resetting the values to be
empty; this was worked around by using another config
file, $(BUILDDIR)lib/iso.mk, and including it later
but that would require a separate target with per-target
CONFIG variable which isn't elegant at all given the need
to actually build up the metadata set.
So the variables were changed (to be more readable anyways)
and then proxied back to BOOT_*. This might be cleaned up
some day after the inclusion order is tweaked or mkimage
defaults get set-if-unset-yet (?=).
As noted in doc/assumptions.txt, the SHELL based target tracing
only works for rules with recipes, even empty but present ones.
The simplest thing to do is hooking "; @:" onto the rule's tail
(one-liner with a non-printing shell builting "true" command).
It looks like the intermediate targets aren't all equal:
some define a finished feature while some create a common
lower level piece of configuration.
Let's do shortcuts for the former so that a distro line can be
more terse and descriptive; help targets in features.in/ tweaked
accordingly.
The package list taken from mkimage-profiles-desktop
and trimmed down due to current TDE packaging difference
as well as extras being defined elsewhere.
ltsp-icewm used to be the only ALTSP (testbed) distro over here
but now its terminal server part works good enough to seperate
it from the UI part.
A few additions to facilitate testing, tweaking and benchmarking:
iftop, openssh-server, mplayer
It's preferred for Razor-qt's logout app to be able to turn
the system off or reboot it; xdm lacks consolekit support.
Thanks Alexander Sokoloff for the hint.
If there's an ethernet interface, a DHCP client, and these
can result in connectivity out-of-box, then it's rather
a feature for almost any LiveCD.
Thus the configuration script is moved from dev feature
to live one with the addition of dhcpcd/dhclient test.
This is asking for some more neat solution though...
As it happens, I've stumbled upon a successfully built image
with alterator-grub in BASE and lilo in install2's installer-steps.
Of course the installer bailed out after dealing with packages :-/
Thanks Leo-sp50 for pointing out the (hopefully) right direction.
So far the tagged scripts concept is too fragile,
and these were used unconditionally anyways.
features.in/Makefile is broken regarding copying
tagged scripts right now...
This one starts up a Firefox session in kiosk mode
(there are several extensions, I find hsv@'s one
preferable) and tries to browse /image/index.html
which corresponds to index.html in the image root
(could be edited by means of e.g. isomaster).
Courtesy of prividen@, there's actual x86_64 client support in ALTSP.
Although led@ tells that it's i586 optimization that hurts on i686+
and should be replaced with either i486 or i686 for that matter...
A larger block size was recommended by led@;
gns@ seems to concur as the 512k value was borrowed
from liveflash.eeepc profile (along with -noI).
The other issue is with binary specific compressors:
x86 was clearly assumed while the data for an educated
guess are pretty handy. Please note that using filters
incurs additional compression attempts for the utility
to choose the best result.
A minimal chroot supporting extension via apt-get;
vitals if built on Sisyphus as of Jan 16, 2012:
i586: 13M tar.xz, 58M chroot (33M w/o /usr/share/{doc,locale,man})
x86_64: 14M tar.xz, 60M chroot (35M w/o /usr/share/{doc,locale,man})
Trivial fixups (extra checks) added to two script hooks.
