I can vouch for this hostname issue.  I just used the --partial restore
option to move my recordings over to some new hardware and I've had terrible
problems.  I now fiund that my new backend shows up as <unknown> when a
frontend UPNP's it.  I'm therefore going to rebuild the new frontend using
the old name and migrate again.

Defo keep the old drive - I've rolled back so many times on a new frontend
trying to get a stable VDPAU install I just cant imagine what I'd have done
without it!
