Which the -xdev option you specify will do anyway...

There's still the issue of using find on other filesystems that may be
mounted (e.g. if there's more than one partition or disk normally
mounted). And then there's group ownerships to consider.

Definitely a good thing to try and not get into the situation of wanting
to change user id in the first place. E.g. by creating all users in the
same order (assuming the systems are all the same distro) which is what
I do as a early step after installing a new system.
