Starting Avahi Daemon in Edgy

OK, this has bitten me twice now, so I guess that makes it a good reason to blog it.

If you find that avahi daemon is not starting for you, then you probably need to set AVAHI_DAEMON_START=1 in /etc/default/avahi-daemon

Twice now I have found that an Ubuntu Edgy install has not started this and twice I have ended up reading init scripts to work out why. So, now we know.
