I don't think that would be enough, because new files with the old
[ug]ids could be created while find is running. Some programs could be
running that rely on the numbers as they existed when they started.
(Some programs could even have uids compiled into them.)
I would like to know how Debian did migrations in the past. It seems to
me that it could not be accomplished without taking the system into
single-user mode.
