upgrade from 7.0pre1 to 7.0pre2 kills networking - from 'configure this server' when you get to select 'server & gateway' tells you that the system has only one nic and so cannot be configured in this mode - only had time to try a couple of different nics and would not recognise them.
Would log this in bugtracker but won't let me log in - "The username or password you entered is not valid."
