Yes, on Red Hat and older Fedora systems, UIDs below 500 are reserved
for system services such as the apache user.

On newer Fedora systems (and most other distributions such as Debian and
Ubuntu), the reserved range has been increased to 1000.

So it's never safe to use an ID below those values. (And as a general
rule, it's best to keep your network IDs above 10,000 to avoid conflicts
with local user accounts as well).
