9f72780d17 Experimental overlayfs support
If aufs not available/broken we could try to use overlayfs.
NB: changes below doesn't work without modified make-initrd-propagator!

e139a5e091 stage2: added broken-down module lists
These were produced off the single sub.in/stage1/modules
file using this scriptlet to prefix/annotate the names:

  grep '\.ko$' modules \
  | grep -v / \
  | while read m; do \
  	echo "$(find /lib/modules/$(uname -r)/kernel/{drivers,fs} \
		-name "$m" -printf %P $m $(modinfo -d "${m%.ko}" 2>&1)"; \
    done

...with subsequent sorting and manual separation.

This is meant to be the second stage in monolithic modules
file split, so the lists themselves are largely unmolested
otherwise.  The plan is to further split those into prefix-
and module-specific ones.

Add a note clarifying 10-stage2's status, by the way.

1ee01498d5 stage1, stage2: moved propagator modules file
What was a static sub.in/stage1/modules (and the only one)
is now features.in/stage2/stage1/modules.d/10-stage2
(basically a compatibility file that might go some day).

It will be auto-picked as its name corresponds to the
NN-SUFFIX pattern specified in stage1 subprofile now
with $(FEATURES) going into default STAGE1_MODLISTS.

8faf140777 kernel, stage2: rearranged initrd hooks
stage2 has been thinking it's synonymous with propagator
and used to usurp kernel's belongings either; carefully
tear scripts apart so that kernel feature makes sure
initrd gets generated, and stage2 (which is still all
about propagator) cares for its bits.

e3571f276a stage2, efi: added kernel config test collector
The newly-introduced STAGE1_KCONFIG variable serves
to keep those kernel configuration options that are
required to be present in the kernel to boot.

9d495f26cb stage2: preload ahci before udev/propagator
This change tries to force loading the storage driver
for cases when SecureBoot is "helping" the chainloader
to fail, see #29705 for details collected so far.

Of course ahci.ko only does AHCI but that's every storage
controller I've seen on UEFI/SecureBoot systems so far.

6139571a8b stage2: fix 10-initrd-base for current make-initrd
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.

e9f60f007c 03-test-kernel: silliest mistake II
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.

bd427df77a stage2: updated 80-make-initfs
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.

c30490e2e8 80-make-initfs: fix the silliest mistake ever
*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.

90b8fd49f4 80-make-initfs: fixed silly thinko
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

12a2fc983c 80-make-initfs: fix for current make-initrd*
Thanks mithraen@ for spotting, boyarsh@ for explaining,
and legion@ for hearty support :)

The problem would manifest itself like this:

  No such file or directory

8989fc2771 added plymouth feature
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+)

74e5734eae 80-make-initfs: optimize for newer make-initrd
legion@ implemented skipping depmod call, and that's several more
seconds for most of the images; let's shave these off if possible.

8d16069882 stage2: squashfs blocksize tweaks
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.

fe58c46ead stage2: tunable squashfs compression
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.

94b2052bfb stage1: halve squashfs block size
gns@ has 512k, led@ suggests that it's too much a bit;
let's try 256k.

178a700e6e 03-test-kernel: tweak squashfs compression
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.

96e89d0062 s/subst/sed -i/g
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.

f5a8b89381 stage2 based live subprofiles, updated docs
- 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
