education: use use/power/acpi instead of +power because this leads to a forced shutdown [distrtest-3933]

Previously, you had to specify two parameters MKIMAGE_PREFIX and
GLOBAL_PREFIX with the same value - the path to mkimage. And this
behavior has not been documented. The GLOBAL_PREFIX variable is
defined in mkimage in config.mk and rules.mk.

rtc not needed in initrd.

Not needed more. uuid assigned directly in configs.

make-initrd supports adding module directories.

Since we are now using fuuid, it doesn't depend on mkimage version.
But it depends on the propagator version.

As new exfat filesystem is merged into linux-5.7 kernel, exfatprogs is
created as an official userspace utilities that contain all of the standard
utilities for creating and fixing and debugging exfat filesystem in linux
system.
std-def kernel in Sisyphus 5.10.

The parameter is used to save the intermediate tarball used to
build the virtual machine image.

SVGZ is more than a hundred times smaller than PNG.

Wrote that it's a bashism myself and neglected
to specify the proper shell, sigh.

This SHELL manipulation could ruin tracing
piggybacked onto it within lib/report.mk
but it's too late at this stage anyways.

The first half of both pipes was clearly a copy-pasted
initial logfile processing; the file can be of considerable
size (e.g. several megabytes) so it might be slightly more
efficient and cool (but a bit more arcane) to use bash(1)'s
process substitution along with good ol' tee(1) like this:

$ echo -e '1\n2\n3' |tee /dev/stderr 2> >(grep 2 >STDERR) |grep 1 >STDOUT
$ head STD*
==> STDERR <==
2

==> STDOUT <==
1

That "clever hack" with two rev(1) invocations
seems pretty stupid to me: too much processes
and processing instead of simple prefix removal.

One can also have that as ${var##*/} when dealing
with a shell variable and avoiding extra forks, BTW.

..making it fit 80 columns while at that
to avoid horizontal spaghetti code.

Just a cosmetic fixup (until not paired up with translations):
"2nd" means "second", "1st" meant "first".

Needed to execute command:
inxi -G

plymouth might better be used through the corresponding feature
(it's the single place to know how it performs on various arches),
and some other packages are just missing.

This package is requisite for updating "boot" (Elbrus firmware).

The missing glob resulted in disk images properly
partitioned only for e2kv3 ("e2k" for historical
reasons in ALT), and v4+ ones only got a single
ext4 partition that wouldn't work with current
MCST's Boot code.

So we are can to build compressed img files.

Suggested by testers.

Celluloid segfaults on Jetson Nano, so use vlc there, but keep
celluloid for other aarch64 systems.
