There's still an annoying problem (a race?) manifesting itself
as installer bailing out between packages installation and lilo
setup with X segfault in logs; while the culprit is not known yet,
let's avoid that for most images by moving the bootloader request
from the former "leaf" target (which noe became a "node") into an
experimental server-systemd one.

Thanks Leo-sp50 for bringing that to my attention again; see also
