Just a guess, but it probably could, if you didn't use the UUIDs to
mount the drives by. Such as you mounted them by device names, or
volume names. Though, I think it'd be best not to have cloned IDs.
Briefly looking at RAID information, there are things that should be
unique, and there are some things that can be duplicated (not so sure
that they should be, though). Drive IDs would need to be unique for
anything that uses IDs to differentiate one drive from other. There's
partition and volume IDs that are used for different purposes.
I agree. But it’s hard not to use UIEDs and to ignore misconfigured UUIDs. Many Fedora
tools use UUID by default, e.g. Cockpit and - if I remember correctly - dbus. Therefore,
cloning a disc often ends up in more work than cloning saves.
