Although this is true, one thing we could do is set a default hostname
that is static ("fedora" or similar is fine), and teach the utilities
used to join an AD/IPA/etc.. domain to generate a new random hostname if
they detect the hostname is the generic "static" one.
The hostname is used in the install-time-generated disk volume names
(/dev/mapper/fedora_myhostname-home), so changing it is confusing.
