Fix conflict installer-distro-junior-stage3 with
installer-distro-education-stage3.

There was something wrong about that order of additives
and the base configuration; let's make it straight,
putting the foundation first and architecture-dependent
additions on top of it.

Note that double-colon syntax is specifically allowing
for multiple rules adding up their recipes (and prereqs),
but all of those rules must be specified as double-colon
(this was violated in the previous state of alt-server.mk).

There aren't any supposed there so far, anyways.

This package contains both the fan control service
(disabled by default so sort of safe) and the manual
fanspeed.sh (that we rather need to provide out-of-box).

Still have to refer to MCST instead at the moment...

Not much use, and spoils postinstall.d messages with
FAILED (to mount the already-mounted flash drive).

Tested to work in practice.

The problem at hand is that sem@ explicitly disables acpid
within installer-distro-simply-linux; early shots at
ALT Education 9.0 for Elbrus suffered from this as e2k's
power button handling differs slightly regarding events
generated so we *do* need acpid{,-events-e2k} to poweroff
on power button press.

Hope this doesn't introduce regressions or woes for anyone.

...instead of custom slinux/misc-base hack incompatible
with the current p9_e2k.

Finalize the move to shared multiseat support on e2k
following education.mk; should have been done properly
in the first place but I couldn't manage that for 9.0,
let's at least fix this now.

This includes merge of RELENG-e2k-edu private branch current state
along with the move to shared multiseat support on e2k and assorted
updates following pkg.in/.

...by providing common targets for 801-PC and 101-PC distro needs.

This should have been done when reworking Workstation,
but better that late than making a copy for Education.

NB: directory name has been chosen to both sort late
    (so that functionality related checkboxes come first
    and graphics setup related ones sit down there), and
    to relate to X11 as well.

Obsoleted by proper handling within office feature.

There are literally no office packages on riscv64 so far,
let's ease the need to count that in within pkglists like
it was done in slinux/misc-base since this approach makes
for unreadable conditional chunks if we look at LO-still
being absent on e2k; a common place should be in place.

Added use/office/LibreOffice/lang/extra target inspired
by pkg.in/lists/slinux/misc-base as well as targets for
two more LO subpackages; and use/office/LibreOffice/full
so that distros don't have to reiterate on all of those
particularities.

Some pkggroups were numbered (thus ordered) and some weren't;
let's make those uniform instead of depending on Latin alphabet:

kde5 -> 06_kde5
teacher -> 07_teacher
server-apps-edu -> 08_server-apps-edu
video-conferencing -> 09_video-conferencing

There's no full KDE Plasma 5 environment available on e2k yet
but many libraries, frameworks and apps are there already;
I chose to provide a distinkt pkggroup so that this subset
doesn't get confused with the whole KDE 5.

...thanks gimagereader for showing up the need in those
(its preferences include a table of language names
written in the corresponding languages).

...so that gimagereader can scan in Engrish too.

Not every package is available on Elbrus, avoid the missing ones;
add mplayer along with vlc just in case as it's better optimized
for e2k already (including MCST patches and automatic use of more
than one CPU core).

...but teamviewer is not.

DRI3 is fine on e2k now.

There's no std-def kernel on e2k and mipsel so far, and there are
different kernels for some aarch64 machines as well;  we'll have to
deal with this problem that's been solved in m-p-d the other way
around (@KFLAVOUR@ substitution in pkglists among the rest).

Also add graphics branding part: must be there regardless of platform,
otherwise an arbitrary one gets pulled in, this time it was
"xalt-kworkstation".  This is another case of the same problem,
m-p-d would solve it with @BRANDING@ substitution where m-p does
generation of variable contents but not file-based pkglists to
be put into the image for runtime selection during install process.

Restrict plymouth support to @X86 as well, just as bootsplash
branding component has already been.

Not much use, and spoils postinstall.d messages with
FAILED (to mount the already-mounted flash drive).

Should help those interested in using servers as workstations
as well (SM718 would only do 800x600 with vesa driver).

This commit includes summary of the work done within RELENG-alt-server
branch, and goes over the existing bits regarding architecture support.

It was somewhat hard to keep separate so I finally chose to lump these
parts together.

These have been brewing in RELENG-alt-server branch for a while;
with ALT Server 9.0 for Elbrus release as the immediate result.

NB: plymouth is still strangely broken there.

...so those willing to use e.g. 256-colour terminal variants
can do so without extra access to the repository.

...or the friendly alterator-pkg bails out silently.

Four checkboxes with "Elbrus 801-PC" prefix look a bit too much,
let's put these under a parent one; the counter-argument is that
selecting that parent checkbox is going to provide message telling
that there are conflicts within -- the proper widget would be a
dropbox with the number of seats but we don't do that just yet
in alterator-pkg.

The autologin group goes there too; still a hack that should be
replaced by proper alterator-users multiseat support.

...as suggested; enable if installed.

This has been suggested by a customer.

The MCST's binary translator allows running x86 code
on e2k architecture; see also http://altlinux.org/e2k-rtc

SYSLINUX happens where GRUB happens too, just in case.

The problem at hand is that some branding-*-bootloader tend to
*create* /etc/sysconfig/grub2 without bothering to check that it
existed, thus confusing the subsequent scripts (e.g. 65-serial.sh
tries to run update-grub that's just absent then).

Otherwise it might e.g. add branding-*-bootloader
for no good reason, poisoning $destdir with an
existing and non-empty /etc/sysconfig/grub2
regardless of the actual grub availability
on the platform.

The point is that it's common between the rest of the arches,
no need to keep making my old mistake of growing configuration
trees based on very different "roots" (.e2k-installer this time
which was good for early experiments but not for production).

Also get rid of long-unused distro/alt-workstation-?01 targets,
unified kernel made those obsolete.

And last but not least: *drop* that setup-libgl-dri3-disable,
makes Radeon RX lag (half-recent AMD GPUs seem to lack 2D part
rather altogether, it's emulated through 3D).
