When I installed I was given no option to set the host name of my computer (perhaps as I was not connected to a network at the time).
I have since edited /etc/hosts and /etc/hostname to finally get the hostname I wanted.
I have noticed (while trying to figure out why the host name failed to change first time I tried) that the ssh keys stored in /etc/ssh all relate to root@old_hostname.
These keys, I assume, were set up at install - how do I change them to relate to root@new_hostname?
Or does it not matter if they don't match?
