I'd like to know what the logic is behind the 1000.  Certainly picking on the
linux distro I have to hand:

UID_MIN                   500
UID_MAX                 60000

auth        requisite     pam_succeed_if.so uid >= 500 quiet

Taking a look at SuSe, we have:

SYSTEM_UID_MIN            100
SYSTEM_UID_MAX            499
UID_MIN                  1000
UID_MAX                 60000

What's it reserving 500-999 for?
