Well, but it has been used in the past, and as definitely something we
should support in one way or another. Which is why we have this:

https://fedoraproject.org/wiki/Features/nssmyhostname

and 

http://www.freedesktop.org/wiki/Software/systemd/hostnamed

and there are even people working on sending out change notifications
from /proc/sys/kernel/hostname in the kernel.

The user might want to change it? DHCP wants to change it? Name conflict
in the local network, and Avahi wants to change it? Of course, the
latter we don't necessarily want to do by default, but they are valid uses.
