services feature works like this:

  1. enable whatever services are in DEFAULT_SERVICES_ENABLE
  2. disable whatever is in DEFAULT_SERVICES_DISABLE
  3. enable services in SERVICES_ENABLE
  4. finally, disable those in SERVICES_DISABLE

So one should not disable display-manager service!

Disabling prefdm is not needed as it doesn't start
when display-manager.service symlink exists.

- pkgpriorities feature (manowar@)
- extended e2k support

Yes we've got e2k-*.iso images by now!
Should see quite some deduplication though.

Elbrus-801 and -101 are now added; 401's support refactored
and modified to cover 4.4 server system as well.

These clearly aren't final but have been stabilizing
for quite some time already, let's just merge.

There's no qemu there so far, and there's no need
to fiddle with setarch either.

NB: part of this commit erroneously went into
    1c777c8a
    quite some time ago, sorry about the mess.

It's legit here as I know no Elbrus users among
non-Russian-speakers, at least so far; should move
to generic l10n feature (which will definitely see
its glory by then).

This is to avoid extra actions when one actually needs
KOI8-R (which is still hardwired in some lcc messages).
Should all be rolled into l10n feature some day...

The early scheme consisted of boot.conf template
with a separate hook filling it in; this was nice
for serial console setup script which could just
amend the kernel command line as needed _but_
this got changed towards the more generic scheme
(breaking the hook in question, unfortunately).

manowar@ had some experiments with usbflash-based installer,
and we needed a git-server chroot as well.

Let's provide a more competent multi-system rescue image
while keeping some rescue bits common to all of the others.

It needs (and has) no isolinux in the first place;
this is also the situation with most or all non-x86
arches, the code should probably reflect that.

There was no thunderbird built for e2k for a while,
and some images might benefit from a lightweight
GUI MUA; the only question is whether it belongs
to workstation classification or not really.

This reverts commit b98bf15a:
we've got imsettings built for e2k as well now.

This one supports multiple kernels (and tweaks boot
labels aiming to simplify target kernel selection
for the CPU at hand) instead of an earlier attempt
to fill in a template.

No need for the template so just drop it.

This was crucial for e2k rescue image supporting
multiple CPU versions but can be useful elsewhere.

Wonder why it was missing for so long...

This has been made a bit messy with commit
9f72780d,
just split the "involved" and straightforward
checks into two.

It's not a blocker if enabling online repos fails;
we should provide a better handling of warnings
with e.g. a summary of those after build.

This one might probably change into core functionality but right now
it should help when you get not the branding, init system, or whatever
alternative you do _not_ need.

- antohami@'s improvements

It was noted that Ancient Cyrillic glyphs aren't available
out-of-box (and people wondered why there are no Chinsese
glyphs before), so adding proper Unicode font looks worth it.

This flavour is likely missing a lightweight graphical
file manager with great features.

Enlightenment does not provide its polkit agent.
Added a lightweight polkit agent without dependencies
on a specific DE; it won't be autostarted though.

These two should improve rescue image usability
for system provisioning.

The reason for all of them is simple: a modern webkit-based browser.

The particular justification for each is:
- lxqt: Qupzilla is officially deprecated in favour of Falkon;
- kde4: Rekonq simply doesn't cut the mustard;
- kde5: Firefox is fine but there's more suitable one.

We definitely don't want to see rekonq anywhere,
it's grossly incompetent as a web browser;
and Qupzilla is now being developed under KDE
umbrella and the new name Falkon.

Kernel packages we have on this architecture use
uncompressed vmlinux file called image; handle that.

These changes were actually recorded as needed for
vm/e2k-builder but let's put these into a common base
for the win.

It has no VM hypervisor so far, the images are intended
for bare metal execution.

This one is actually refactored on the base of
41b5a5b6 and fd4f2a67 commits but let's consider
it to be the first released one ;-)

It's 15 Mb off x86_64 regular-rescue.iso as of today
(libicu and a few other hefty libraries are only needed
for fio), and benchmarks are probably a better company
albeit fio could be useful as a stress testing tool.

...following its dropout from sisyphus:
http://git.altlinux.org/tasks/archive/done/_198/203122/

There's a problematic dependency chain as of today's sisyphus:

smbios-utils => python3-module-smbios, python3, python-base

python3 => python3-base => python3-test

python3-test => python3-modules-tkinter => tk => libtk => libX11

...and libX11 is explicitly banned in regular-rescue.iso
which is determined to stay text-only; let's drop this package
until this problem is resolved.

librsvg is requires to display svg icons in some apps;
e.g., lightdm misses some of those without it.

Remove compton-conf: not needed without compon itself
(which rather looks abandoned), and would need an update
from 0.1 to 0.3 anyways.
