[Nottingham] Two Entries in /etc/hosts

Thanks for the input Jason. Is it really the case that the hostname command
can set other entries in /etc/hosts (which is what I want to do)? I thought
it could only set the hostname of the machine it was running.

Looks like I could use netctl to run an arbitrary command upon connection
to a home network:

I've used wicd before. Maybe I'll go back to it if I can't get netctl to do
what I want.
