d9dca6cb1a doc, grub, stage1, stage2: Add support multiple kernels for grub only
At the moment, the ability to select the kernel with which to boot is
implemented only for grub (grub-pc, grub-efi, ieee1275boot).
note that renamed STAGE1_KFLAVOUR to STAGE1_KFLAVOURS, as multiple
kernels can now be added.

e447b4c7df stage1: Also add STAGE1_KMODULES
It is very strange that earlier in STAGE1 added kernel modules from
a variable STAGE1_KMODULES_REGEXP only.
This commit makes the drm feature work properly.

01a1581b71 Revert "stage1, stage2: allow multiple kernels"
This reverts commit 02a5231ba5.
Upstream mkimage has not yet take patches to support packaging
multiple kernels to ISO image. In order to avoid problems, have
to revert this commit.

26cf322550 stage1, stage2: move af_packet to 50-stage2-net
af_packet rather belongs to networking stack
than to common module library indeed.

f9f1437bfe stage1: added ext4.ko to modules
It's been found out that live_rw isn't going to work
without ext4 module being available; let's ensure that.

559f80adf3 a few modules.d test drives
These are aimed to test the modules.d/ and auto-pickup
implementation as well as to present an example.

At least 50-net might change (or just get renamed to avoid
auto-pickup) some day as the "net" feature's meaning is
to provide networking upon bootup and these modules are
only needed within stage1 if we're going to netboot;
and that's quite different thing.

armh-cubox bits are prone to get renamed/generalized too
since e.g. ArmadaXP based server images are going to need
this as well.

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.

a36d0236a4 stage1, stage2: initial modlists support
stage1's got prepare-modules target collecting
modules file snippets all over stage1/modules.d/
subdirectories within individual features.

stage2 now adds names of all the features going into
a particular image as snippet file suffix list so that
individual features don't have to register themselves
twice (as a feature and as a propagator modules.d
snippet carrier).

This is going to allow both "uncommon" modules getting
included with no problem (sin@ has wanted cifs ones
for quite some time, for example, and some want e.g.
infiniband modules) *and* to reduce the actual list
below the common mark as well (which is the case with
live-privacy image, for one).

And stage1 memory consumption does matter in some cases
as it's highly critical with no chance to use swap yet.

08d802ab0d stage1: drop dummy.ko
Looks like it's been dumped in along with the rest but not
actually used in {make-initrd-,}propagator; the problem with it
is that snd-dummy.ko matches and pulls a bunch of unrelated
modules where these don't belong (grep -w wouldn't match
snd_dummy.ko though).

bc0f8a45ee stage1: re-add a few modules
These can be found in (semi-)supported branches still:

- loop.ko:
  + 3.0.101-std-def-alt0.M60P.1
  + 3.4.96-led-ws-alt0.M70P.1
- aufs.ko:
  + 2.6.32-el-smp-alt31
  + 3.4.96-led-ws-alt0.M70P.1

ehci_marvell.ko isn't found in contemporary sisyphus/armh
kernels but let's purge it later during archdep rewrite.

NB: libusual.ko has been renamed to usb-libusual.ko as of p6
    (not to be found in p7 anymore), and nls_base.ko was in
    2.6.32 kernels as of p6 but not there in p7; purge these
    somewhere down the road.

71ad34a9bf stage1: fix module name

f112a3358e stage1: add USB3 support
This has been missing for *so* long somehow, and adding some 200k
of modules for fast hardware that's widely available by now
looks like a deal.

Added USB Attached SCSI module just in case (or rather for weak
crc_t10dif symbols?).

6f452182fd fix kpackages() API
This function's got its argument order chosen for "aesthetical"
reason of $(2) following $(1) in the macros but the logical order
is exactly the opposite: we care for kernel flavour much more than
for module set (which is dependent upon it).

So while silent dropout of kernel-image if KFLAVOURS is set
but KMODULES is empty could be fixed by testing for $(2) only,
it looks like a good time to fix this discrepancy altogether.

49b6291a40 kernel, stage1: don't provide r8168.ko by default
It conflicts with r8169.ko inobviously.

The whole mess looks like this:
- r8169.ko doesn't work for all of Realtek 8111/8168/8169 mutations
- r8168.ko works with some of the chips r8169.ko doesn't
- r8168.ko also works with many chips r8169.ko works with
- r8169.ko is provided by kernel-image package (thus default)
- r8168.ko is provided by kernel-modules-r8168 package (optional)
- kernel-modules-r8168 package requires r8168-blacklist package
- r8168-blacklist package is a one-liner that blacklists r8169.ko
- STAGE1_KMODULES wouldn't include r8168 (std-def) or rtl8168 (led-ws)
- sub.in/stage1/modules would mention r8168.ko (m-p-d: r8169.ko)

So a LiveCD built with use/kernel/net might work with RTL8111/8110
just fine when booted live but fail to automatically load the module
when installed onto hard drive; manual modprobe r8169 would work though.
NB: some of the chips (those available to me) would work just fine
both ways -- this has contributed to fixing this *that* late.

Bottom line:

  do not install backup/kludge drivers overriding main ones by default!

Thanks sem@ for providing the crucial hint.

3f547e2504 documentation: use paths relative to toplevel dir
This change is done to reduce ambiguity in some cases;
the previous intention has been to ease navigation when
staying in a particular directory, now it's been changed
in favour of convenient toplevel `git grep' in fact.

Both variants have their pros and cons, I just find myself
leaning to this one by now hence the commit.  Feel free to
provide constructive criticism :)

Some path-related bitrot has also been fixed while at that.

429ce58608 added live_rw support
There's a need for a separate boot target since
persistent storage is way slower than tmpfs indeed;
usbflash has a tendency for huge performance drops
given simultaneous writes in addition to reads which
are the bottleneck already.

make-initrd-propagator 0.18 introduced ext4 rw slice,
so the corresponding kernel module needs to be included
into stage1; see also #28289.

NB: not available on x86_64-efi (or hybrid GPT to be strict)
due to fragility of the hack being made: parted(8) panics
upon seeing that, and good ol' fdisk is unable to treat it.

NB: use/live/rw use/rescue/rx use/syslinux/ui/gfxboot
are unlikely to play very nice together due to the latter's
magic l10n: "session" label is taken by live_rw config snippet
and *is* translated in design-bootloader-source;
OTOH "rescue_session" is *not*.

35689d158d stage1: replace r8169 with r8168
The issue is that r8169 is rather broken nowadays while
r8168 tends to work on the same hardware; see also #28473.

Thanks zerg@ for having hinted that it's stage1 modules,
not the root squashfs.

The initial approach required some quite involved postprocessing

6f5be91827 make-3.82 adaptation
The issue actually hit image.in/Makefile: "metadata" target
in features.in/metadata/lib/50-metadata.mk wasn't reached
even if features.in/build-distro/lib/90-build-distro.mk
would ACK that the "whatever" actions included "metadata";
thus Metadata/pkg-groups.tar wasn't created and the installer
silently failed to install the .base system.

Let's armour the rest of the cases where the order of inclusion
might be important as well.

86c42e2db6 implemented {THE,BASE,LIVE}_PACKAGES_REGEXP
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.

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.

180ed5359c "if test ..." replaced by "if [ ... ]"
Fixed up the remnants of the early style mix
to correspond to the proposed doc/style.txt;
the rationale being that

	if [ ... ]; then
		...
		...
	fi

is the more readable construct among itself,

	if test ...; then
		...
		...
	fi

and

	[ ... ] && {
		...
		...
	}

due to the condition being more distinguishable
when bracketed and the body more apparent as the
one inside "if" and not any other block; the less
obvious difference is that the final construct of
the latter form is prone to the whole script exit
status being non-zero if the condition isn't met.

d6972a39bf introduced THE_{KMODULES,PACKAGES,LISTS,GROUPS}
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.

774169c6cd COMMON_PACKAGES and SYSTEM_PACKAGES
It was clear that "common" isn't very apt for packages that
will get *everywhere*, and became apparent when the need for
a "base+live packages" variable arrived with powerbutton feature.

So:
- the former COMMON_PACKAGES are now SYSTEM_PACKAGES;
- COMMON_PACKAGES act as "BASE+LIVE_PACKAGES".

Note that SYSTEM_PACKAGES also got factored out from stage2 based
features into stage2 subprofile itself; cleanups were due as well.
