I don't think there is an official term.
But there is one more option to look at: IgniteUX. You can copy your boot disk to tape and then boot the tape to rebuild your disk. This requires a tape drive. I understand that Ignite can work over a network, but I've never done that.
See
this thread for more info about ignite. There are more Ignite threads too, search for Ignite* to find them all.
