- armh fixes and tweaks

This one is IMHO best suited DE for cubox' meagre performance
(especially on I/O side due to microSD) as it incurs quite modest
I/O, CPU and RAM footprint quite suitable for PII-300 times
(cubox feels quite like that but has lots of RAM compared to
even maxed-out Pentium II workstation).

The image includes OpenSCADA as a nice and unique feature
which has been developed with TDE environment in mind
and was used on ARM hardware like N900, incidentally;
thanks aen@ for this suggestion.

Thanks rom_as@ for the entire OpenSCADA project and
packages as well as for keeping TDE packages alive
and kickin' in Sisyphus.

Most of these are slated to employ oem feature by now,
no sense to call it in almost every dependency chain;
the only image left with predefined locale and credentials
is cubox-xfce-ru.

The nuance being that:
- alterator-setup package would change default.target
  for systemd providing a symlink of its own and making
  a backup of what was there (rc3 basically);
- 40-x11-autostart would ignore that backup;
- 99-oem-setup would do nothing about it all either;
- alterator-setup removal would restore rc3 symlink.

It's not pretty either, something more robust should be
invented some day.

Basically forgot to add after initial testing.

It came unnoticed that USE_IFPLUGD clashes with
CONFIG_WIRELESS which is the default for eth ifaces.

It's a bit heavy but still works.

That one conflicted with alterator-setup
by removing what it needs... should be done
differently.

Really no need to test and sleep when there's sync mode.

- control and sound features

It used to be a hasty static string; something like
"ALT Linux regular-e17/x86_64" seems more relevant.

The extent of this feature's action should be clear
as well as its prerequisite.

rootfs presented a special case when there is no resulting
directory at all as it gets merged with the target subprofile
by design.

Still those features adding only rootfs scripts need to depend
on it but this resulted in an attempt to process a missing subdir.

This is brought back to sanity now.

`make check' must be included in my release process :-/

vm/.cubox-gtk already pulls +nm in, no need to do it again.

Few things:

- extend feature specification
  + SysVinit can be chosen explicitly via init feature,
    no need to keep sysklogd in yet another pkglist;
  + power management should be included too
    (both cpufreq setup and power button handling);
  + LILO seems to be heavily preferred among the
    target audience :)

- use desktop installer for regular-server
  + the seeming controversy is explained easily:
    installer-distro-altlinux-generic has very few
    modules to the point of being inconvenient for
    anything but quick rounds of basic testing,
    and distributions rather do need network setup
    along with a non-privileged user.

The funny thing while debugging this was "how the heck
could a sound related change induce privilege related shift?"
-- turns out that udev-alsa (which pulls in ConsoleKit)
was the culprit... looks like LXDE hasn't dumped it yet :)

Factor of 2 is not enough for kernel upgrade due to filesystem overhead.
Add BOOT_SIZE_FACTOR on top of that.

Maybe the conditionals shouldn't be too terse, by the way...

...instead of setting up pam_mktemp ourselves
even if that was no big deal too.

As 50-sudo-su script cares for sudo and su control facilities no more
that hook is aptly renamed to 50-sshd-root (should be generalized
either some day).

...instead of having to do the same by hand.

TODO--, and this one was pretty expected
after the "invention" of iterators.

Setting NM_CONTROLLED is apparently not enough to disable
/etc/net handling of a particular interface; thanks sem@
for noticing the fortunate error messages in logs
and explaining this peculiarity to me.

50-root script uses passwd(1),
mea culpa
for having optimized it out...

The main reason was use/net but warranting the
bits needed for proper pulseaudio functioning
via use/sound seems also logical.

This bunch of commits was done so these can be
mixed and matched (or even reverted) later if needed;
it was tempting to just revamp things wholesale again
but coarse grained approach is worse to maintain.

One of the earlier duplicates pruned now.

The client side might benefit a bit more in the future
but the server side does not (and should not) require
everything client side does; thus use base ALSA target.

An act of deduplication again.

gnome3 was just asking to line up either.

use/live/sound target is dropped on the floor,
there were no more in-profile users of it.

This replaces the many sets of the corresponding packages
wandering all over pkglists, features and configurations;
the interface should be rather well-defined by now.

That trailing "; @:" makes up a cause to run a shell,
and SHELL is overloaded with tracing for reports.

Thus an omission fixup.

use/live/install stopped to provide a desktop icon; the nuance is
that zdg-user-dirs-install.sh script in livecd-install package
expects ~/.config/user-dirs.dirs to actually do that.

- cuboxism

This script hook used to lurk in live feature but was deemed needed
in cubox images too; thus it's time to move it into a standalone
feature (maybe a configurable one, even).

Thanks glebfm@ for initial shot and sem@ for discussion.
