Finally got the joys of Clonezilla up and running on multiple PC’s. Actually worth the effort when a normal install is about 12 hours of slog mostly typing in the terminal window. Just over 3gb per minute over sata is a lot quicker to nip back in and do a few edits – so each machine has its new identity. Found Clonezilla Server too although the pc’s involved were too “old” for it to run at a reasonable screen resolution unfortunately. I do feel like i’m creating sheep but so long as they all BAA when they should all is fine.
