Xfce used to present artifacts with compositing disabled;
now that it's fixed compositing can be disabled to increase
performance.

NB: firefox-gnome_shell_integration will turn into a pumpkin
    after firefox 74!

...introduced with the previous commit.

There are use cases when having this common knob would be desirable.

I've long wanted to have this nice helper around in m-p too
but might have set the bar too high.

The "prorper integration" idea was to have the script check
just those pkglists which are relevant for a given image IIRC.

Let's toss it in to begin.

Just reasonable given the server/kvm pkglist.

Those willing to reuse archdep-filter elsewhere
will likely have to figure it out from Makefiles
anyway, so probably not worth overdocumenting...

Duplicating the architecture tag handling logic was afwul
indeed; one-liner (well, two lines for readability) is not
that bad at least, factoring it out wouldn't gain a lot.

This code started breeding within pkg.in/*/Makefile,
and it was lacking both E2K (as a generic alias,
not just "e2k or e2kv4") _and_ the ability to negate
selection, as in "everywhere but not on any e2k").

Let's fix all of that at once, and parallelize sed
execution as well; my tests with 1000-line file
containing "a b c d@!E2K e@e2k f g@!X86 h i@IA32"
lines show roughly 3x higher CPU load and lower
execution time (~0.3 sec vs ~0.9 sec on 801-PC).

And turn that code snippet into a proper filter
with inline edit capability (I've dropped the exit
trap as failing to mv signals a disaster anyway).

...so that bits required for PXE boot are handy in the image.

It's required to set BASE_BOOTLOADER variable,
otherwise grub will get in *too*.

Not used by systemd and looks obsolete generally
as sysvinit-based disk images aren't really targeting
low-resource systems these days _by default_ but rather
_can_ target those as well; feel free to reconstruct
these "RAM saving" bits as a part of e.g. lowmem patch.

bfk3 needs more than 10 seconds to bring the interface up
and get the lease.

TODO: make this configurable.

sm750 is seen as framebuffer-only device, so it's not marked with
master-of-seat tag with current udev (which does this mostly to
dri cards). But without master-of-seat device logind does not
report that the seat "CanGraphical", and thus sddm does not
work for it; there might be other problems, too.

This change adds udev rule that marks sm705's fb device as
master-of-seat.

We only plan to distribute XZ-compressed rootfs tarballs.

Tavolga seldom has a serial port connected, so it makes
more sense to write kernel and systemd's messages
to tty1.
