This needed for blueberry.

Left only mtp backend for Android devices.

NetworkManager not worked without udev-rule-generator-net on sysvinit

...as cloud-init will do that.

Use polkit-sysvinit as a workaround.

Reverts: 08d93ed8
(and several slightly more involved places)

...to extend the supported protocols list as suggested.

cinnamon-regular package doesn't pull thunderbird in anymore,
so drop the l10n package too.

Looks like the initial empirical rule "mixin must not depend
on another mixin" is too restrictive for practical purposes
given enough image targets multiplied by enough platforms;
let's declare it obsolete and see what follows.

These fonts are provided by use/live/x11 target, but they are
also needed by all desktop regulars, not just live builds.

This might be further refactored/generalized it seems...

...into mixins to make the distro configuration
more reusable and portable across target arches.
Think grafting instead of just growing from seed.

sddm doesn't work with sysvinit currently, so this
mixin is not a good place to specify the display manager;
and different platforms may have different needs,
e.g. sddm has just stopped working on aarch64 boards.

caffeine is not needed anymore as xfce-power-manager has a presentation mode.
newmoon browser is not maintained in ALT's repositories for quite some time.

It's only included in kde5 flavour anyways :-)

Also added qasmixer in mixin/regular-xfce-sysv

firefox-classic_theme_restorer is not there anymore
(following pre-quantum fx29+ australis it countered):
http://git.altlinux.org/tasks/archive/done/_222/227910/logs/events.1.2.log

...since wmaker doesn't autostart anything.

With the arrival of elogind in sysvinit, the polkit agent is needed
within all builds using it.

elogind provides sessions for polkit; use/init/sysv/polkit
and use/deflogin/sysv/nm are not needed anymore,
polkit-agent is needed instead.

This mixin will be used for non-x86 image builds.

chrony is a modern ntp client working better than openntp's one
in many circumstances (especially on e2k hardware).

It's missing in Sisyphus altogether:

regular-xfce-sysv doesn't use xfce4-full so still needs a screensaver.

xfce4-full now provides its own xfce4-screensaver

It is wrong to make it impossible to use the default browser
(firefox) for targets using mixin/regular-lxqt given the
caveat with setting a variable to X, then to Y, then to X
again through make targets (see e.g. bootloader feature's
README).

mixin/office contains packages for solving typical office tasks
