systemd-settings-disable-dumpcore will soon be removed from Sisyphus and p10.

glibc-gconv-modules is also needed.

xscreensaver has more than its main package and the details
of what to get where might be confusing for some of us;
in particular, there are 2D and 3D hacks collections
(and some arches would rather prefer to avoid 3D for now),
desktop file sets aimed for MATE/Xfce, and the frontend.

So let's provide some basic reusable targets.

...so it supports H.264 media; should be fixed
by making it use ffmpeg4 some day hopefully.

clinfo and friends might come handy these days,
and the whole group isn't very obvious.

Looks like this helps installers with 5.4.0-2.20 based kernel
to install fine on Elbrus 801-PC with Radeon RX 580.

pwmd is finally available on all of v3/v4/v5 subarches,
and there's an installer feature for v4/v5 specifically.

...both primary and secondary.

A part of a half-hearted attempt to update live-0ad.iso
(no x86 hardware was handy for testing it anyways).

This one is somewhat different for readonly optical media
(where [auto]mounted disk is a nuisanse) and writable USB
Flash or even fixed disk (where it's too easy to destroy
data by missing the right letter).

...so that it's more applicable to a wider set of images
(those lacking e2k-alt-linux' specific labels just won't
get broken default boot target label name for no reason).

...otherwise a whole-disk block device would be accepted
by the script but not by the firmware's bootloader.

Optical media isn't to be checked for those of course.

alt-rescue-20210811-e2kv5.img would fail to initialize
proper videomode on an Elbrus 901-PC with Radeon R7:

[   16.742051] [drm] Loading oland Microcode
[   16.743850] [drm:si_init [radeon]] *ERROR* Failed to load firmware!

Looks like a plain omission.

Rollback from use/x11/nvidia/optimus to plain use/x11/nvidia
for now as I don't have a proper x86 stand to test it now;
feel free to revert this part if you do and bumblebee works.

There is no need to specify serial console here because it is now
specified in the use/uboot.

firefox is absent in sisyphus_riscv64

I've doubted what to base it on but settled with ve/.lxc-base
for the common prefix reason. :)

Part of mkimage-profiles' design is to make it easier
to figure out the common parts and describe these as such;
even if something's hastily implemented through copypaste,
it's worth it to have a look (amending the debugged commit
to make it pretty as well, fixing up the newcomers at the
merge time, or at least spotting crap and taking care
afterwards -- the latter having more potential for "free"
merge conflicts, doing this sort of cleanup rather earlier
than later rather pays off albeit premature optimization
can take place here either when too many "layers of
beforehand indirection" are introduced; ve/.lxc-bare
in this very commit is bordering just that, so use your
common sense and experience or ask in devel-distro@
when in doubt).
