Many distributions have rc scripts that set it automatically, from a saved
config file.  If you run Red Hat Linux, the data is saved in
/etc/sysconfig/network Make sure you put the whole name there
(host.domain.ocm) not just the hostname part.

For that to become totally effective, you have to reboot, but you can
change the active hostname with the "hostname" command, but some
applications won't recognize the change until they're restarted.
