Hostname's behaviour depends on your current effective UID. So the
undesired effect of setting the hostname to anything supplied as a
parameter to hostname only works for root (or another super user with
appropriate priviliges).
The main problem here seems to be the fact that Paul downloaded an
unknown, unverified script from the net and executed it as super user.

Shall 'laphroaig.castle' be a fqdn???
Anyways. I can only tell what I know from HP-UX where it generally is no
good idea to have the anything but the fqdn set as the host's name.
