This one was requested by Andrew Churashev; please note
that the image in use must contain recent flash plugin
so that at least the already known vulnerabilities are
more or less plugged in it... and Sun Java plugin isn't
going to get secure either.

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).

There's no need to repeat the typical openssh-* triade
all over the place; those who need server and client
are better off pulling in "openssh" pkglist, and those
needing a particular package should specify it.

There's no need to disable console as it's emulated too,
and it still can be helpful or just convenient.

The "vm" name became a bit confusing with the introduction
of build-vm feature; let's call this one "vmguest" until we do
hierarchical (sub)features.

Finally tired of expr(1) quirks,
and even ash(1) does $((arithmetic-expansion))!

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.

After we have built a bare virtual machine image successfully
some variations are due, and these are to be described here.

installer-feature-no-xconsole depends on stage2 bits and is
NOT intended for installed/live systems at all; let's move
to the proper stage3 based one.

Was mentioning REPORTS while the variable name is REPORT.

Don't allow systemd to set LANG for all processes.
See ALT#27408 for details.

Turn on xdg-user-dirs by default.

Workaround for ALT#13213.

$(IMAGE_NAME).$(IMAGE_TYPE) -> $(IMAGE_NAME)-latest-$(ARCH).$(IMAGE_TYPE)

Allow to put the log files and reports in a custom directory instead
of IMIGEDIR.

- new features:
  + initial build-vm
  + plymouth

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)...

autologin won't register a consolekit session, and gnomes
are too greedy regarding sessions to let us go unmolested...

This particular image isn't production ready when built on
current Sisyphus yet due to unresolved NM/dbus problems
but I decided to at least archive the reached state.

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).

The second shot at an image worked out;
MATE packages are not in Sisyphus yet, use

rpm http://autoimports.altlinux.org/pub/ALTLinux/autoimports/Sisyphus $ARCH autoimports
rpm http://autoimports.altlinux.org/pub/ALTLinux/autoimports/Sisyphus noarch autoimports

These tweaks were suggested by rom_as@
based on his continued m-p-d work.

distro/.live-desktop also changed to depend
on use/plymouth/live

(mike@: actually no sense to set both
KFLAVOURS and STAGE1_KFLAVOUR to the same value
since the latter is derived from the former)

Keyboard accelerators rather make sense
with menu/vesamenu UI.

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+)

- minor bugfixes

The more or less basic desktop appeared to lack
base locale support (starting with glibc-locales).

It somehow managed to evade me that $(TMP) might be uninitialized;
definitely should be checked before stuffing into sed substitution
command.

NB: this could be done in pure make but my take was less readable.

Thanks shadowsbrother/gmail for hitting and reporting this.

legion@ implemented skipping depmod call, and that's several more
seconds for most of the images; let's shave these off if possible.

- docs updates

It might be spottable but not immediately obvious that a feature
lives entirely in features.in/FEATURE and every target it provides
is described in the corresponding config.mk; thanks dkr@ for asking.

It wasn't exactly obvious that the actual image build
isn't started with CHECK=1.

It appears that while splitting off main.mk we've lost
the ability to pass e.g. ARCHES via custom configuration;
thanks dkr@ for spotting this.

Whoops, forgot to feed placeholders for git to grok
the empty directories that are needed later...

It wasn't articulated clearly enough that features are strictly
incremental (while variables can be overridden).

lightdm-1.1+ handling had to be corrected
regarding the separate greeters.
