The image and the installed system may have kernels with different KFLAVOUR.

Command-line copy/paste utilities for Wayland.

kvm isn't universally available, let's at least mark it this way.

This one fixes the "cooler goes off during installation"
10.2rc problem on multi-CPU e8c2 motherboards that follows
misinitialization of sensor drivers (lacking i2c mux init
_before_ them) and subsequent misreading of zero degree
temperature for CPUs (would need no cooling if it was true).

It only makes sense on engineering samples of .404 board,
and 201-PC is .480 with only a single 4X PCIe gen3 slot
that needs riser to get a reasonable videocard connected
(manual multiseat setup is a minor hurdle it seems).

We don't do ship vivante drivers since p9_e2k
as those behaved erratically with gtk+3 at least
(and were a major PITA to handle in the first place,
and nobody asked in the end: folks just needed 2D+Xv);
so no sense to bring extra noise into installation.

See the .318-01 related story in a nearby pkg.in commit.

The reason is that there were several batches of
4-port .318-01 based 801-PC systems shipped specifically
as multiseat ones (with two RX570 or three simpler GPUs),
and it's more reasonable to provide out-of-box support
for those in a new release instead of having to resort
to manual setups with alterator-multiseat, messing with
the installer-provided configuration by hand or giving up
(or, well, building a sideline installer images with
custom udev-conf packages).

e2kv4 with mga2  is e1cp (Elbrus-1C+);
e2kv6 with mga25 is e2c3 (Elbrus-2C3).

xorg driver is the same.

e1cp and e2c3 have tricky GPU driver modules that can misinit
given the lack of other modules they don't directly depend on;
let's provide softdep lists so that the prereqs do get loaded.

The problem is with indirect module initialization dependencies
(the infamous "Driver probe function unexpectedly returned 256"
error when loading the module from initrd and not full rootfs);
let's provide modprobe with a hint.

...accordingly to the package getting renamed.

201-PC has been developed using .404 motherboards
(IIRC using the two middle PCIe slots for GPUs);
1601-PC one has been done with .466 motherboard
by sciberia.io guys who have outrun me at that!

The packages might need more tweaks and PCIe slot
specifics in documentation but the configurations
were taken from real systems.

It's an artificial name albeit my workstation (nee build server)
is dubbed e1601 at work, but it's still beta than nothin'.

It's actually set within the corresponding apt-conf
but referring to that here is better than tossing
REPO=http/pvt all over the make runs.

There are two reasons to use/power on Elbrus:

1) current kernels generate "button" event for ACPI
   power button press instead of "button/power";
   systemd doesn't grok that, and acpid needs special
   configuration to (which needs to be fixed properly
   in said kernels but just not done yet -- mcst#6148);

2) installer-feature-e2k-power is useful on e2kv6
   as it configures e2k-pcs-cpufreq to autoload.

See-also: http://www.gnu.org/software/make/manual/make.html#Double_002dColon

PS: e2k-pcs-cpufreq uses to be builtin, *argh*

ACPI power button event differs for some reason
(plain "button" instead of "button/power"), and
both acpid and systemd need special training to
cope with that (mcst#6148); let's at least make
it work in a release.

Works on server/workstation but surprisingly not with education:

It's pretty useless by now IMNSHO given the typical USB flash drive
as the installation media and online repos -- and *seems* to have
problems with flash-based installation:

Running postinstall script [90-pkg.sh] /dev /
/
mount: /media/ALTLinux: /dev/sdb1 already mounted or mount point busy.

...as it rather introduces red ink for no good reason:

Running postinstall script [90-pkg.sh] /dev /
/
mount: /media/ALTLinux: /dev/sdb1 already mounted or mount point busy.

It should do some work: nothing else might have pulled use/x11 in
(which brings another topic to the table: we'd probably better
have some platform-independent targets that pull archdep pieces in
under the hood).

Fixes: 2002e625

Looks like it can get stuck for quite some time on serial ports
that are present and might be occupied by other processes already.

Typing this on an e16c based workstation but 201-PC seems more
likely a target for now.

mpv backend seems to go parallel either with no configuration needed,
or on more media types.

NB: the missing modules break image build,
    avoid mga2/galcore/vivante by default
    (absent in some CPU-specific kernels).

There is no need to set std-def, it is already default on those
architectures where it is available.
Uses package list 'kernel-headers' allows to not depend to specific
kernels.
