That can be done, sure. I'm not really sure how all these things are managed, so
I don't know if we should allow one thing, the other, or both.

I imagine that the 'domainname' commands and 'hostname' commands should work,
and I don't know how to test further.

Setting "networking.domain" does not make the command domainname work, in my
system.

Maybe someone can throw some light on this? What sense there is in having
hostname and domain apart in networking?
