Well, it's not as simple as it might appear. "hostnamectl set-hostname"
actually sets the pretty hostname (and should do that unaltered), then
strips all the weird chars and sets the result as the unix hostname. You
should always have the pretty hostname in place.
The idea is that "Lennart's PC" as pretty hostname becomes "lennarts-pc"
as Unix hostname.
