This list has nothing to do with lxqt.

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!

This commit is packing a bunch of changes that went
into RELENG-e2k-workstation during its forked
development; it covers three distinct things:

- boot.conf preparation for firmware to load the image;
- fixup of packages common for e2k images;
- major cleanup of obsolete/unused cruft
  (unified kernel and reliable xorg autodetection
  allow us to move away from canned machine-specific
  configurations for the most part).

...to any installer: tends to be useful, documented already.

These deserve to be distinguished already.

elbrus-def works for me on either of 4c, 8c, or 1c+ based systems;
call it properly then.

...instead of hardwiring the particular variant;
this one is switchable down the road at least.

The commit is a no-op otherwise.

...as these targets are now considered worth the name.

101's one has been useful enough so far.

The goal was simple: every use/e2k/{x11,install2}/$MACHINE
must be self-sufficient regarding platform support, that is
it must depend on the corresponding CPU-specific target.

A bit less make-tech but still better overall.

NB: llvm cleanup is not needed anymore after upgrade to
    Mesa-17/llvm-3.7, should be dropped like this year.

This one started with pulling use/init/sysv/polkit
out from distro/.e2k-installer since there are now
some systemd-based e2k installers as well; it looks
better to provide two distinct intermediate targets
(and leave polkit-sysvinit up for the distro ones).

Yes we've got e2k-*.iso images by now!
Should see quite some deduplication though.

manowar@ had some experiments with usbflash-based installer,
and we needed a git-server chroot as well.

Let's provide a more competent multi-system rescue image
while keeping some rescue bits common to all of the others.

These changes were actually recorded as needed for
vm/e2k-builder but let's put these into a common base
for the win.

This one is actually refactored on the base of
41b5a5b6 and fd4f2a67 commits but let's consider
it to be the first released one ;-)

mixin/e2k-desktop was asking for separation from its day zero,
and the rest just came in naturally (the temporary patch to
add lxqt and mate looked awfully with all the duplication in).

...and somewhat improve vm/e2k-xfce.

Let's build an Xfce based image, got anything needed (well, almost:
xorg-drv-libinput isn't there and no one is crying over that here).

And let's change "e2k" suffix to be prefix while at that.

These used to carry (or need) their own means for the same
problem of extra services consuming bootup time.

These images have been tested on an Elbrus-401 PC.
