Users and groups properly organized?

[Kristian Vaaf]

Hello.

Have you all ever had a look at your /etc/master.passwd and /etc/group?
Stupid question. But notice the user and group identifications being thrown
about as if they didn't matter. To me they do, and I would like some order
in my system. Starting with my user and group identifications.

Can I do something like this?

find -s . -uid foo | xargs chown bar
find -s . -gid foo | xargs chgrp bar

To be able to arrange master.passwd like this,
where UIDs and GIDs go by a chronological order?

Maybe such order, harmony or balance or whatever will help
boost system performance? Just a superstitious thought. Cheers! :)
