Chapter 15. Users & Groups: mininal UID for normal Users
Chapter 15. Users & Groups is not decided on the minimal value for UIDs/GIDs:
All normal users and normal user groups will
be above the uid/gid of 100. No system required
uid or gid is to be placed above uid/gid 99 as
this may clash with real users imported via
NIS or LDAP from other Unix systems. (FIXME:
What about Red Hat's use of 500 for this? Do
other Linux distributions all use 100? Is there
another standard we can reference which contains
the 100 rule?)
Checking some Linuxes I realized that more Distributions avoid UID´s <500
for normal users. This is good becauset some time in the future 99 system
users could be not enough.
I think, we should recommend or even require the UID range
of 101 to 499 to reserved for future assignment by the
Linux Standard Base.

Here are some observed values: (Please add yours for Systems not listed yet)
Caldera LTP:
1st user:grp = 500:100
Suse 7.0:
1st user:grp = 500:100
RedHat 7:
1st user:grp = 500:500
EasyLinux 2.2:
1st user:grp = 1000:100
