Sorry, I have been reading a bunch of Debian documentation, and this is
from their developer's reference:
10.2.2 UID and GID classes
The UID and GID numbers are divided into classes as follows:
0-99:
Globally allocated by the Debian project, the same on every
Debian system. These ids will appear in the passwd and group
files of all Debian systems, new ids in this range being added
automatically as the base-passwd package is updated.
Packages which need a single statically allocated uid or gid
should use one of these; their maintainers should ask the
base-passwd maintainer for ids.
100-999:
Dynamically allocated system users and groups. Packages which
need a user or group, but can have this user or group allocated
dynamically and differently on each system, should use adduser
--system to create the group and/or user. adduser will check
for the existence of the user or group, and if necessary choose
an unused id based on the ranges specified in adduser.conf.
1000-29999:
Dynamically allocated user accounts. By default adduser will
choose UIDs and GIDs for user accounts in this range, though
adduser.conf may be used to modify this behavior.
I didn't realize this was so Debian specific.
