live user is configured for build if builder-useradd is installed.

This makes installing from livecd cleaner, making it unnecessary
to remove the live user in the preinstall script.

Why are they there?

Now cinnamon-minimal is provided from cinnamon.
Also, there is no point in the additional base metapackage.
No need to prevent the user from removing remaininig пакеты with the command:
apt-get autoremove

The configs can be atypical, so changing the path can make it
work incorrectly.

live/image-scripts.d/50-var-run-fix clash with
rootfs/image-scripts.d/50-var-run-fix.

livecd-run-hooks runs hooks from /image/live.hooks/ by default.

live must not contain installer-feature-*-stage3.
In live this work is done by:
features.in/x11-autostart/rootfs/image-scripts.d/40-x11-autostart

This script does what hasn't been needed for over 10 years.

If xorg-dri-* is not needed, just don't install it.

livecd-webkiosk conflict with livecd-runapp.
The regression was a commit 2968101c.

Need for debug alterator-vm.

use/plymouth/vm is not needed, because use/plymouth/base is the
target that needs to be achieved when building the vm image.

rootfs scripts are also run when building live image. But assigning
BASE_BOOTARGS to live is not required, since the arguments are
copied from STAGE1_BOOTARGS by the installer.

Reducing the size of the image is relevant for all architectures, and
everything else is no longer needed.

Useful tool for testing the 3d subsystem; we use it a lot
on aarch64 and riscv64 systems.

Now thunderbird is available in sisyphus_riscv,
so there's no need to substitute claws-mail for it.

SBC usually have wi-fi on board.
+wireless adds wi-fi support for rescue. This is extra garbage in
the generated profile for vm.

CRDA is no longer needed as of kernel v4.15 since commit 007f6c5e6eb45
("cfg80211: support loading regulatory database as firmware file") added
support to use the kernel's firmware request API which looks for the
firmware on /lib/firmware. Because of this CRDA is legacy software for
older kernels. It will continue to be maintained.

It seems it's required most WiFi dirviers to work properly,
so let's make sure it's present.

Needed for Sifive Unmatched (riscv64), but may be useful for other SBCs
as well.
Reported by iv@

package includes too many dependencies.

Instead of showing a warning, it is better to explicitly specify
the SYSLINUX_UI=none option in the config.

gnustep-Popup removed from Sisyphus with message:
"Uncompatible with new gnustep-base".

Despite the fact that the package has a livecd- prefix, it makes
changes directly during installation. At the same time, changes
are made to the configs, and deleting the package does nothing.
This behavior is not allowed for installable livecds.

The installer has been adapted to work normally with method=disk when booted from cd-rom.
Using method=disk allows you to remove the iso label from the burned flash drive, which
in turn allows you to manipulate partitions in gparted. It should also help with programs
of writing that remove the iso label.

The package will be built from another branch now.
This needs to be done to enable separate branches with their own
spec and .gear/rules to build images and containers in hasher.

If the default keyring is missing, then chromium at the 1st start
importunately requires the user to enter a password for the keyring.
pam_gnome-keyring allows you to automatically generate a keyring
with the user's password.

At the suggestion of Mikhail Efremov <sem@altlinux.org>
pam_gnome-keyring has been added to the general list,
since keyring can use not only chromium.

For some firmware (e.g. firmware-alsa-sof).
