Apparently all but first parameters are passed to xen.efi, so it is possible to
select which config section should be used. This makes xen.efi copy
unnecessary.
Anaconda/pungi doesn't support multiple versions of the same package at

directory and install them in %post script.
...even if NetworkManager is running.
Actually it is started by anaconda (and needed to provide D-Bus
interface) even if service disabled in systemd configuration.
