As was proposed by Alexey Varakin in community@,
whdd was built for ALT Linux by drool@ and pauli@
with some help by torabora@ and mithraen@; looks like
it's a worthy addition to the rescue kit.

The problem manifests itself when the naive parser ignores
any conditions that might have been set in the makefiles
included with subsequent attempt to run a target which has
its actual rule defined within e.g. "ifdef DEBUG" clause
(as is the case for conf.d/test.mk); that will fail with
no proper diagnostics currently.

Maybe this would be of some use (but then again maybe not):
http://stackoverflow.com/questions/3063507/list-goals-targets-in-gnu-make

The previous part was fixed and discussed in commit
c30490e2;
so much for a deduplication effort...

This would result in almost immediate

  make[1]: *** [profile/populate] Error 2

as well.

That is, p6/t6 continue to use 3.81 (while providing 3.82
alongside with it), and Sisyphus has moved to 3.82 before
p7/t7.  We support both versions by now.

While ildar@ has some reason for the slimmer image
the somewhat standalone one is documented in examples
for offline use, ruining it in-place is not an option.

Let's just do a split (and lose a target-specific variable
example in favour of a commodity pkglist by the way; oh well).

a live-builder appliance is (or may be) usually used for building software
with many dependencies, hence needing access to external resources,
e.g. apt repos with lib${NAME}-devel packages.

This commit cuts RPM packages from the live-builder LiveCD.

- initial uefi, luks, armh support
- enhanced arm, gnome3/systemd, vm support

The issue (#28002) resulting in vm image build error reading

  Syntax error at or above line 5 in file '/etc/lilo-loop.conf'

was caused by fdisk-2.22 changing its "-l" option output format
to drop the very mention of the long irrelevant crap named "CHS".

The problem is, however, that we still need that crap to piggyback
a loop device's fake geometry to lilo while installing it there.

Reported by icesik@.

Somewhat kludgy unfortunately and might need even more tweaking,
I have only armv7l board handy at the moment to verify that
the transformation is going to work.

QEMU is bailing out here and now ("Exec format error").

Example sources.list.sisyphus.armh of the season:

  rpm http://ftp.altlinux.ru/pub/people/asdus/sisyphus armh classic
  rpm http://ftp.altlinux.ru/pub/people/asdus/sisyphus noarch classic

An example for sam9x25-ek:

make \
 PACK_UBI_MIN_IO_SIZE=2KiB \
 PACK_UBIFS_OPTS="-e 124KiB -c 1984" \
 PACK_UBI_OPTS="-p 128KiB -s 2048" \
 PACK_UBI_VOL_TYPE=dynamic \
 PACK_UBI_VOL_NAME=rootfs \
 PACK_UBI_VOL_FLAGS=autoresize \
 HSH_EXCLUDE_DOCS=1 ARCH=arm APTCONF=apt.conf.sisyphus.arm ve/generic.ubifs

It's beta too but holding off the feature seems counterproductive.

Based on timonbl4@'s advice; might need some bleeding edge
packages right now, feel free to ask (everything should be
in place by p7/branch though).

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.

Tagged scripts got heavily postponed
for the lack of practicability
so far.

Both do require postprocessing (see http://www.altlinux.org/UEFI)
until mkimage receives xorriso support and efiboot.img is passed
down there somehow, but it's beta than nothin' so far.

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.

Thanks ildar@ for both the request and clarifications
regarding the build of the minimalistic GNOME3 LiveCD.

NB: current GNOME3 is hooked on systemd.

Introduced distro/.live-desktop-ru as a shortcut for
distro/.live-desktop use/live/ru which occurs several times
already (and the counter will increase right now).

systemd is a tricky beast: getting it to actually launch gdm
required considerable effort on the part of stupid myself.

The relevant links:
* https://wiki.archlinux.org/index.php/Systemd#Running_DEs_under_systemd
* http://unix.stackexchange.com/a/35626/15296

Still looks pretty dirty, and there's some duplication
with a hook in features.in/slinux as well.

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.

- regressions--

Thanks go to ildar@ for spotting this: my ~/.mkimage/profiles.mk
routinely contains DEBUG = 1 line which effectively masked this
regression in commit 307fb51f.

Wouldn't be a big deal but syslinux.iso is recommended in
tutorial docs being slim and fast-building, and it's also
what's buildable locally in live-builder.iso environment.

ildar@ noted that the test involving whitespace is too
quirky for some quirky enough cases like

  rpm-dir file:/var/cache/apt/archives . x86_64

-- let's introduce word boundaries there.

*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

The newer kernels have versioned NFS support code moved
into a few separate modules with nice self-explanatory
messages reading "Protocol not supported" if one has
managed to overlook this; thanks boyarsh@ for heads-up
(based on f545923271f9d1938d1887632ab4697c4c009039 m-p-d).

- docs subpackage (HTML/PDF book)

The initial sketch did work but was somewhat redundant
while lacking the knob conveniently change output directory
as well as means to get it cleaned up.

Thanks torabora@ for the tip along with reference to his
http://altlinux.org/asciidoc page.

Docs should live happily together, after all,
and toplevel should be more or less uncluttered :)

Adjusted/rewrote as appropriate as well.

It was actually an experiment leftover and spoils
toplevel completion so let's drop that one, just
as mentioned by torabora@.

It's not fun to boot into a livecd just to find that
there's no lspci around!

- diffable logs
- AMD APU support
