If alterator-setup >= 4.0 it only runs when it detects
'systemd.unit=setup.target' in /proc/cmdline.
If alterator-setup version <= 4.0 there will be a problem in the
form of the remaining argument 'systemd.unit=setup.target' in
/proc/cmdline.

the creation of a symlink was broken, since there is a default.target

The default language is configured in feature l10n.

BASE_BRANDING variable does not use.
Fix for commit: a2ca3620

/usr/sbin/install2-init-functions is provided by several packages.
Because of this, extra packages are installed. It is necessary to
simplify the task for the packages manager.

The network can be controlled via NetworkManager without ETCnet
configs. DHCP support needs to be added to other targets.

Needed alterator-setup 0.3.13.
Now alterator-setup to prepare self to work via VNC.
Also VNC mode is now optional and requires inclusion
in/etc/alterator-setup/config option ALTERATOR_SETUP_VNC=1

This change sets the default root password to 'altlinux'
for all the images that employ use/oem feature.
This password will be reset by the configuration wizard at
the first boot and cannot be used to login
to ssh even if it's enabled out-of-the-box. So, 'happy
path' user experience of our distros does not change;
but it helps in troubleshooting the cases
when alterator-setup cannot start e.g. due to broken
graphics.

installer-common-stage3 configures network. Without it,
net-eth step of the OEM setup does not work properly.

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

But with git might not work.

Empty lists/.base needed for alterator-pkg to calculate the space
required for installation when selecting groups.

This target needed for alterator-setup (pkg step).
Also added preinstall and eth-net steps.

This target disable cleanup install packages after finishing
alterator-setup.

Run installer features during install via rootfs.

Network interface managed by NetworkManager is not activated when
alterator-setup is launched.

This is an experimental and known incomplete support
for the system configuration that has to be done at the
first boot-up by its user since it's their choice.

This draft uses systemd which has been a requirement :-/
Thanks sem@ for helping out with the somewhat tricky
unit file for alterator-setup.
