Actually, as part of work, I need to backup and restore disks and after *much trying/testing* I chose clonezilla.
I dont recall offhand but you can change UIDS. OTOH for us common folk dev names not uids make life easier.
There are usecases where UIDs make sense, but in general (ouch) it's unnecessary complexity.
But clonezilla will look after all the gritty stuff, including UIDs]
