THE_* and friends are all unneeded for live builder image;
this commit makes dev feature basically incompatible with
install2 feature (which relies on the conventional behaviour
of main subprofile), will have to think it all over if the
combination of these two ever becomes needed.

It feels like time to introduce regular-builder.iso,
let's help it by factoring most of the common part out
into the feature.

Might be useful for those wishing to set up additional drives
carrying NTFS at install time.

This was basically a feature request to get smartctl into
sysv-tde starterkit; it's in regular+extra which is pulled
for regular/starterkit rescue images already but it's better
to have it duplicated here than missing somewhere as the tool
is pretty requisite these days.

It's not supported anymore:
http://git.altlinux.org/tasks/archive/done/_133/136193/

It's been ignored since the introduction of deflogin feature
and removal of build-vm specific ROOTPW variable handling;
might be adjusted to mandate this for vm/bare too, have to
think it over.

There could be root-only VM appliances, for example,
and ROOTPW is now handled through this feature.

- docs: "7.0+" (closes: #30474)
- l10n feature

Thanks someone at opennet for bringing my attention to this:

0.6.3 has introduced some changes that were deemed incompatible
with t6/p6 branches; it should be possible to restore compatibility
at least for non-EFI images but the effort required hasn't been
up for grabs so far.

The problem with initial implementation (commit 62e7e9c1)
is that there's no systemd-services package in p7/branch
thus apt complains about an attempt to remove something
that doesn't even exist in the first place.

Aimed at live images at first but should cover installers as well.

This has been brewing for quite some time and while the proper
implementation is considerably more complex (and hard to do)
looks like there's demand for the particular important use case,
namely LiveCDs for Russian users, so this code has been shared
with a few people before merge.

There's a particular problem with lazy evaluation
in case of BOOT_LANG: mkimage uses internal variable,
BOOT_LANG = $(GLOBAL_BOOT_LANG) (note the lack of
immediate assignment there), and if we set up

  export GLOBAL_BOOT_LANG = $(BOOT_LANG)

in the same namespace we end up with recursively
defined pair of variables; a ":=" in either place
would save the day _but_ it's not there in m-p due to
accumulator variables, e.g. USERS, which are defined
and exported by a corresponding feature and then get
populated *after* having been declared for export,
_and_ it's not in mkimage as of 0.2.16 for some reason
that might even be good (I don't know yet).

- current updates

It has evaded sisyphus before but not anymore.

...yet another one...

This has been asked for by lewellyn@freenode, why not.

NB: distro/.regular-sysv doesn't include use/net-eth/dhcp
    (as it looks like asking for) since there's still hope
    to get NM cooperating with sysvinit again.

Looks like there are more fonts out there than just croscore!

- minor tweaks

Both locale and keyboard have been set up already,
no use to waste time on those (which results in 'us'
keyboard layout missing out totally, ironically).

Thanks aris@ for the tip.

...basically giving it a chance to go with Secure Boot undisabled
which is a feature these days, unfortunately...

installer-feature-cpufreq-stage3 has been deleted from sisyphus.

This one adds write intent bitmaps for MD RAID;
see also #14877.

It's been asked for already, let's not wait for December:
http://www.opennet.ru/openforum/vsluhforumID3/99418.html#48

It's been obsoleted by lxqt-config in 0.8.0.

Those URW fonts are scarey by today's standards :-(
Unfortunately these are pulled in by seamonkey & co...

- pkglist updates

This package holds a nice collection of unofficial utilities
to deal with OpenVZ containers.

There are quite a few potentially useful packages
implementing FUSE based (userspace) filesystems,
these are typically lightweight and still might be
helpful to someone stuck with our rescue image...

This one lurked under my radar so far as well.

ALT Linux LiveCD/Rescue images use AUFS currently,
some tools to access unionfs might be useful.

Wonder how it managed to evade this list before...

xfdashboard is a GNOME Shell-like window switching interface
and application runner; xfce4-whiskermenu-plugin is another
(KDE-like) menu search facility; thanks sem@ for suggestions.

It's a pretty solid PDF viewer;
pcmanfm-qt integration to be sorted out later.
