There was a somewhat subtle Makefile->main.mk rename leftover
lurking in "everything" target: the default Makefile got used,
not the supposed main.mk -- which resulted in an attempt to
get way too much job done (the number of builds per target
became $ARCH squared, not just $ARCH).

Huge thanks to led@ for being an inspiring pedantic!

A minimal chroot supporting extension via apt-get;
vitals if built on Sisyphus as of Jan 16, 2012:

  i586: 13M tar.xz, 58M chroot (33M w/o /usr/share/{doc,locale,man})
x86_64: 14M tar.xz, 60M chroot (35M w/o /usr/share/{doc,locale,man})

Trivial fixups (extra checks) added to two script hooks.

mkisofs can use hints on file disposition; this needs some
support on mkimage side but that's pretty trivial (hope to
see it in 0.2.2+).

Referring to install2 subprofile after it got generalized
and renamed to stage2 is an omission, better fix it late
than never.

It's burdensome for testing but at least the result
is somewhat useful then.

The point is to give Colin S. Miller the credit for
a hack to get the current goal's word-in-a-list position:
http://lists.gnu.org/archive/html/help-gnu-utils/2010-05/msg00004.html

The dependency is actually long gone since the current hack
is to just replace hardwired "grub" in an installer-steps
with whatever got configured...

As was found out by Vladimir Karpinsky (thanks for patience!),
the autochosen directory might still have too restrictive mount
options -- nodev and/or noexec.  Hopefully the diags are a bit
better and faster by now.

It happens that if the host environment isn't particularly
tuned up for package builds already then bin/mktmpdir might
come up with a directory outside hasher-allowed prefix list;
now that's a shame and not a Christmas gift, clearly.

Thanks Vladimir Karpinsky for pointing this problem out too.

It was briefly mentioned in QUICKSTART but somehow managed
to evade the commandlines provided.  And while at it, let's
make errors like this more explicit to avoid extra lookups.
Oh, and fix QUICKSTART so that readers miss the hassle. :)

Thanks Vladimir Karpinsky for pointing this problem out.

Avoid extra files where a variable would suffice; and use
the more specific "syslinux.list" rather than a "files.list".

We can do textmode live images, after all.
Some sort of autologin would be useful there too
but doing it right is less obvious to me at the moment...

- multi-target, multi-arch, single-job builds

doc/variables.txt was missing the already-existing BUILDLOG
variable description, and ARCHES got added during multi-target
toplevel rewrite.  Other minor fixes come as appropriate.

The fallback case of building in a brother directory moved
from the last line of code to the first one becoming more
explicit along the way.

Support for slash-containing argument (being a tmpdir name
template prefix) has been added.

The former toplevel Makefile is now toplevel main.mk;
this change allows for multi-target, multi-arch processing
in the current toplevel Makefile.

As the "build" symlink semantics change quite considerably
when one is doing bulk builds (several pruned builddirs might
be useful for comparison), BUILDDIR is now much more likely
to be recreated: the cases when it will persist are when it's
either a single-image build or when the prefix hasn't changed.

There are some more or less subtle bugfixes and enhancements
all over the map as well.

Done within 20111230..20120102 timeframe, actually...

First, let's not do rsync --delete on an unverified target dir
again: the lesson was learned during a subway hacking session
and I must say that SSDs are frightening fast (even if it was
more than a second to realize what happens and terminate the
extermination before it got /home, thanks xterm).

Second, let's use a variable for common name and make's own
realpath function instead of external binary.

At least it shouldn't bail out when the anticipated file
just isn't there...

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.

*_PACKAGES and *_LISTS shouldn't inflict copypasted blocks;
we can iterate over these just fine.

NB: dump-*, not dump_*, due to namespace pollution hurting
debug target if done the latter way (in case someone misses
the morning tea as wel).

As current devmapper doesn't allow for simultaneous
mounts of virtually the same device by different names
(signalled by "Device or resource busy" when trying to
e.g. mount /dev/sda2 but with /dev/evms/sda2 being just
fine), EVMS triggering such behaviour but rarely needed
should be avoided altogether until a hook to disable it
is in place.

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.

- it wasn't firmware-carl9170 but firmware-carl9170-1.9.4
- firmware-linux Obsoletes: firmware-iwl* since 20110520-alt1

screen(1) is definitely the part of a server;
tmux(1) can also be installed of course.

Thanks vvk@ (#15887).

- THE_{KMODULES,PACKAGES,LISTS,GROUPS}
- incremental development, refactoring and bugfixing

Let's prepare some moderately sane base for future desktop
installers, it's not only icewm around anymore.

As 0.4.0 just came out and seems to be quite interesting,
why not add it to the collection? :)

Package base advice is welcome, of course.

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.

- parameter order fixed to "simple first, then those with args"
  and documented as the preferred one (might be debatable, okay)
- added "lowmem" to live so it avoids a ramdisk but works off media
  (it's a knob for propagator)
- added "fastboot" everywhere (but failsafe install) to make use
  of Linux 2.6.29+ async controller initialization
- every snippet got a trailing newline so that isolinux.cfg is readable

And a fancy makefile to check for shortcut dups!

Some more filesystem related utilities inspired by PLD rescue
are due indeed; but ntfsprogs are obsoleted by ntfs-3g, in fact.

iotop and iperf were suggested by stalker@.

Several targets were used in a duplicated way
that made no harm but no sense either.

"sub/stage2/live" might seem a bit cryptic and not readily
traceable, so let's expand on explanations accordingly.

Here we go with postprocessing priorities along the way
as ISO hybridization has to occur before implanting
final MD5 sum (which must happen earlier than e.g. some
external MD5SUM file generation).

Unfortunately proper dependencies aren't applicable here
(though I'd like to be proved wrong on this one).

Please note that this needs propagator > 20101130-alt9
for automatic mode to work (has also been worked around
in gfxboot case with design-bootloader-source-6.0-alt1).

Thanks rom_as@ for asking about the hybrid image status
and helping out with testing.

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)

$(SHORTEN) is better in the midst of the pipe
so that greps are terminal and can sense the tty
(or the lack thereof in case we're logging further).

Actually there's an added duplication in the form of the
test that was previously missing in pkg.in/lists/Makefile
-- that has to be done properly when it's clear how.

This fully omits pkg/lists/.base generation in environments
that won't make use of it.

The outmost shell loop got replaced with a (hidden) bunch
of targets -- it's somewhat controversial as the inner loops
are still there (but at least don't wrap around my SXGA+).

Full targetization might be beneficial in terms of parallelism
achievable *but* that would ruin git history being generated,
and building a distro configuration takes a few seconds at most.
