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:

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)...

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.
