Since we check for the presence of a theme before enabling it in
the grub config, it is enough to issue a warning.

GRUB since 93a786a00 (kern/efi/sb: Enforce verification of font files)
has enforced verification of font files in secure boot mode. In order
to continue to be able to load some default fonts, they are added to
the built-in memdisk bundled with a signed EFI image and may be
accessed by file name prior the actual default path.

blueberry and gnome-bluetooth removed from Sisyphus.
Instead of blueberry, you need to use blueman, which is actively
being developed and does not require gnome-bluetooth.

In addition to other gostcrypto packages.

We use gostcrypto repo component for build and
gnupg2-gostcrypto can be pulled.
Avoid this.

It can be useful to check GOST hash sums.

More likely a newest hardware will work with un-def kernel (6.1.x)
then with std-def kernel (5.10.x).
Besides 5.10 kernel has issues with CIFS mounting (found by testers
was mentioned in the ad-integration@ mailing list).

For cosmetic reasons: it is not selected checkbox in the installer.

Suggested by testers.
They present in the WS K and Education.

It can be useful, but in rare cases.

Note that Yandex browser is x86_64 only.
Requested by black@.

Discussed with black@: it shouldn't be installed by default.
So move it to extras list.

Not sure if it is needed in the SL.
And it shouldn't be installed by default anyway.
This reverts commit ee17618be561cf4e407d9da9e24a488ac88ecf7b.

Taken from SL list.
Also dict-mueller7-utf8 replaced with stardict-mueller7.

The stardict will be enough.
Thanks testers for spotting.

Drop packages that pulled by mate-default.

Suggested by antohami@: rpi-un no longer updated and un-def can be
needed for some hardware.

For R7 applications.
Suggested by cas@.

Chromium-gost is enough.

For easy onboard configuration (not installed by default).
