The installer works more reliable when loaded to RAM.

evms fails to stop a RAID if a RAID is removed and a new one
is created in its place. The problem appeared after we added
mdadm to altinst.
Reported by mcpain@
NOTE: The problem is not observed in live. Either something is
removed from altinst, or something is not installed.

x11vnc doesn't work when xvt calls a terminal other than xterm.
This is a regression in xinit. Does not work any more:

  xinit <command>

Only:

  xinit -e <command>

But they are not going to fix it.

This feature allows you to set alternatives [1].
For example, like this:

   @$(call add,ALTERNATIVES,/usr/bin/xvt:/usr/bin/xterm)

Also, in the config itself, targets for setting alternatives may already
be predefined. For example, use/alternatives/xvt/% allows you to specify
arbitrary alternatives for xvt:
use/alternatives/xvt/xterm, use/alternatives/xvt/mate-terminal, etc.
However, an alternative must be available.

Fixed a bug with moving the core in a cycle. This only needs to be
done once.

These SBC is not available for me.

Needed to install a minimal system
on the root partition with btrfs

If udev-rule-generator-net is installed on the system, add the interface
naming rules from this package to the initrd. If not, add the standard
udev rules.

The naming conventions for network interfaces on stage1 and stage2 must match.

installer-distro-altlinux-desktop does not develop and there is no
desire to support it. It will also allow to check the
alt-workstation profile on regulars, additional testing.

When installing with a classic installer, this package is also needed.

This feature complements the live image of the second stage with installation
image-specific settings and scripted hooks.

It is recommended to connect using +live-installer to ensure that a typical set
of installer-related features is included.

Unlike the install2 feature, a separate image of the second stage of 'altinst'
is not built, but the live image is supplemented with installer packages in
order to reduce the total volume of the iso image.

Installation consists of two stages:
1. The live image is unpacked, as in livecd-install
2. Install additional packages BASE_PACKAGES and package groups THE_GROUPS as in install2.

Unlike install2, only those packages that are not in the live image are placed in the main repository. This is how the size of the iso image is reduced.
