There is no need to support repositories older than p10. It is
better to think about future ones.

When we enable the installation mode from packages (use/live-install-pkg),
we are left without connected repositories after installation.
Let's fix this.

To avoid being deleted when apt-get autoremove.

To avoid deletion during apt-get autoremove.

Now xorg-dri-armsoc is added in use/x11/xorg (list mesa-dri-drivers).

The mesa-dri metapackage contains all the necessary packages for
hardware 3d acceleration support.

It is not needed in live. It will be installed into the system
when installing from the package.

Install it only on the base system.

After removal from live make-initrd-plymouth were left without this
font.

The installer itself installs these packages and adds them to the
base system. For rootfs, as a rule, these packages are not required.

The kernel has a dependency on bootloader-utils, but this may change
in the future, and then apt-get autoremove will remove bootloader-utils.

Added via use/firmware/cpu.

alterator-vm does not hide unsupported features, so all these
packages should be added.

Not needed in stage2.

Not needed in stage2.

not needed in stage2 not needed in stage2.

This is clearly unnecessary in rescue.

To close a case: need to add to the base system, but not to live.

The installer packages are removed by the installer itself.

Not needed for classic installer.

Using a classic installer gives a number of advantages:
- installation not only from a user session, but also in a separate
boot mode, including via vnc
- installation of additional packages, the ability not to put all
the necessary packages in the live
- no one is involved in the development of livecd-install

They are unnecessary in live.

Target for ifupdown2 subsystem. Currently used in PVE distro for network
managment instead of more frequently used analogues (etcnet, networkd)
due to their limitations (etcnet unable to apply changes, absense of OVS
support in networkd)

These targets are outdated.
