this is a "good idea" by any means, as matching UUIDs across
disparate systems seems completely counter to the purpose of a
"Universally" unique identifier. Perhaps the an exception could
be an OD master and its slave.
except that according Apple this should work no matter what the
UUIDs are. I think they did not really understand the problem.
According to Apple each ACE is specific to a UUID. By design UUIDs
should always be unique to each object. They are generated by
combining the MAC address with the number of 100-nanosecond
intervals since October 15, 1582.
If you need consistent UUID resolution then you use a directory
service to provide that information.
except that this is not necessarily how rsync/scp and tar work. It is
conceivable that their behaviour, when users by the same username
exist on source and target, is meant to match users by username and
only fall to UUID when the match does not exist. This is, mutatis
mutandis (UUID <-> uid|gid), how rsync works by default.
My problem here is that many people talk about the(ir) theory but do
not seem to have done tests.
