Just so you know someone who's had some luck with it, I just upgraded my
HD version of b7 to b8. I did this through the mono web interface
(System->Firmware->Enable Firmware Upload) and then selected the
generic-pc-1.2b8.img file and it accepted it, applied it, automatically
rebooted the firewall and came up as 1.2b8.
