We reduce the img by minimizing free space.

Too many problems with it, not fit for release.

When we build the disk with repository, we don't need to generate anything.
Attempting to generate it results in an error:

  make[3]: *** [generate.mk:10: all] Error 1

This will allow to set the language switch from your keyboard during
installation.

ReadySet is a program to configure the device during the first
installation for non-sisyphus. Users will be created by ReadySet.

The reason for adding only ReadySet for non-sisyphus is that ReadySet
requires Phrog, however, authorization via Phrog is not planned in the
sisyphus image.

The separation of the Flatpak plugin has currently occurred only in the
sisyphus branch.

/usr/lib64/efi/shell.efi was moved to /usr/share/efi/shellx64.efi.
The package is now noarch, so need to check that it is x86_64.
