Booting to Raspberry Pi 4 is not possible with these parameter.

xfce-screensaver has no problems only on x86. mipsel is no exception.

xfce4-screensaver does not work on Tavolga and on
BFK3 with SM750 videocard (see alt#38418). While
upstream does not response to the ticket, we have
to switch to something else.

It's useless for our mipsel images. The office software
from our mipsel repositories doesn't use Java -- even
LibreOffice is built without Java support.

use/oem/distro contains additional steps for executing preinstall
scripts and network configuration.

beesu is a graphical interface for 'su' that can be used
by xdg-su. Without beesu and gksu, xdg-su resorts to asking
root password in xterm, which looks awful.

Otherwise, ssmtpd finds its way into alt-workstation-tavolga
as /usr/sbin/sendmail provider (required by lsb-core).

... instead of adding it manually. This not only reuses
existing code, but also add chrony into PINNED_PACKAGES,
which avoids having systemd-timesynd in the final image.

projectlibre is too slow on Baikal-T.

libreoffice-languagetool is not available on mipsel.

It's now uses just gtk3 and is available on most of the platforms.

It's used by many virtual environments, including PVE,
and was requested by one of the clients for alpha
Tavolga builds.

This package is not available with recent thunderbird.

They work better on Tavolga.

In addition to code re-use, it also pins chrony as
ntp daemon implementation, which helps to avoid
adding systemd-timesyncd into the images.

Available for mipsel too.

This is already done for VM_FSTYPE in a much better way.

There, DTB is named differently.

mipsel-bfk3 feature often serves as basis for special
build for various other BE-T1000-based devices. Having
DTB name in config.mk simplifies creating such derivatives.

To write rootfs images to flash.

lang=ru_RU not needed added into EFI_BOOTARGS, when use grub-efi.
grub-efi use by default.
