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...
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.
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).
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.
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.
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.
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@.
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.
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).
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 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...
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.
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.
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.
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.
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.
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...
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).
Initial openSUSE package base taming effort has shown that
relatively few things should be fixed; subst has been generalized
as -i option to sed(1) since its introduction, so let's just fix it.
Some parts of *image* configuration started slipping down
into the *feature* configuration, and that was wrong; fixed.
Also introduced proper use/live/x11 (via use/x11/xorg with added
wacom support for the sake of #26723/#26724) and rebased the
pre-existing descendants onto it.
As too many things started duplicating between distros proper
and (e.g. corresponding) LiveCDs, it became apparent that a class
of entities which end up working for THE_USER (not a sysadmin,
and not a developer, just a Linux user) is in need.
So THE_KMODULES will power installed basesystem and live image,
while THE_PACKAGES, THE_LISTS and THE_GROUPS will participate
in building those.
This one used to use LIVE_MAIN_GROUPS which seems to be
overlooked substitution artifact from walking over
GLOBAL_PKG_GROUPS and GLOBAL_LIVE_PKG_GROUPS of m-p-d...
(not that LIVE_GROUPS are defined anywhere yet)
use/live/autologin target tries hard to configure any available
autologin means, including a dedicated package and a few DMs.
Thanks gns@ as liveflash.eeepc got robbed somewhat.
It was actually trivial given that the script was already
maintained as a package by enp@ and msp@; its usage requires
one to manually partition the target disk and optionally
mkswap in advance.
The features might get copy-pasted (or even copied-and-pruned)
when initialized; there's an unneccessary duplication of the
function name in the line adding it to FEATURES list, thus
prone to being forgotten and causing some havoc later on.
It was wrong in the first place but tackling this with some
double-colon rules ran into terminality issues, and further
tortures were considered unneccessary.
The current solution isn't perfect (no completely transparent
function name registration upon corresponding target being called)
but at least it is an improvement...
If you make distro/live-builder.iso, the result is an image
containing almost everything (short of actual full enough
repository) to rebuild itself. It will attempt to configure
eth0 with DHCP and reach http://ftp.altlinux.org for packages.
RAM requirements start with 2Gb, self-build is accomplished
on a 4Gb host with "make CLEAN=1 distro/live-builder.iso".
Packages required for "make distro/syslinux.iso" get included.
(some due fixups all over the place too)
MAIN_GROUPS should align better along with MAIN_PACKAGES
and MAIN_LISTS (even if MAIN_ prefix might be suboptimal
given that these packages are essentially extras within
the particular image).
It's still very immature -- base lists should be really base,
and functionality should be sorted out in more consistent way.
So far moved to tagged lists (which need some more experimentation
anyways to get both lists and their use more elegant).
- fixed live.iso (now actually useful):
+ extra cleanup was being done (coming from install2 case)
+ root user was password blocked
+ there was no unprivileged user (added "altlinux" w/o password)
+ added xdm setup hook for future X-based livecd flavours
+ several picks for a less slim "base" list
+ xdm login
- tweaked rescue.iso (added ext3grep)
- introduced generic stage2 subprofile (non-standalone)
- ported installer and rescue over to stage2/{install2,rescue}
- initial stage2/live (needs more work for sure)
- use make-initrd-propagator
- updated and somewhat extended doc/
NB: mind #26133, #26134
