No - you will end up having to change the ACLs every time you add a user.

Much better, but try to avoid those edge cases too!

Try to cut the complexity of ACLs as far as possible. ACLs are
effectively programs and they take a lot of testing when they are

I always try to turn the day-to-day changes into group-membership changes
as then the routine mods are just 'data' rather than 'program'.

One approach you might look at is to use two layers of groups: one to
categorise users by role (printer admin, user-support, accounts) and one
to give access to specific resources (password-writer,
home-address-reader, mail-address-reader). You can then make the role
groups members of the appropriate resource groups, which is a more
understandable way to express policy than typical ACLs.
