There is no point in a feature that adds a two of package lists.

use/slinux/services-enabled and use/slinux/services-disabled do not
require for work adding slinux feature. They need a use/services.

In order to hide warning:
cp: warning: source file 'file' specified more than once

This will save time on identify the causes.

This should be used instead of installer-feature-online-repo.

The image is too large, so remove live from it.
Separate live image will be enough.

Well, why not to add for Workstation too?

See https://bugzilla.altlinux.org/40285,
https://bugzilla.altlinux.org/40029.

...just as server and workstation already do.

SMPlayer's base, mplayer, is currently better optimized
to utilize Elbrus SMP capabilities with auto-threading
by bircoph@; the result runs 4K clips below ~400% CPU
thus making it possible to decode two streams at once
(IOW much better than vlc).

The only downside visible to me is smplayer's update nag.

VLC used to suit everyone (32-/64-bit x86) but not anymore;
let's at least refactor the mess it all turned into by now.

The only non-NOP difference obvious to me should be the addition
of a media player to mipsel variant of alt-workstation; a bugfix
to me as I've first spotted the lack of a mediaplayer in e2k one.

sem@ noted that there were come problems observed with
xfce4-screensaver and advised to use xscreensaver
if relevant.

The initial version of the commit added "base+xscreensaver"
pkglist on armh aarch64 mipsel too but I chose to rather
refrain from messing up/with what I can't even test.

...as well as !riscv64...

NB: IIRC the order was important somehow
so I put the meta-arch before the specific one;
*if* this is correct, then the code handling
the list is not completely correct (or at least
this behaviour has to be documented); not ready
to debug those regexes at the moment though.

antohami: It's not, it's been fixed:
