I have a snapshot of a Gentoo system from 2004 (sys-apps/shadow-4.0.3-r9
and sys-apps/pam-login-3.14). Its login.defs has the following:
#
# Min/max values for automatic uid selection in useradd
#
UID_MIN 1000
UID_MAX 60000
I see the same values in sys-apps/shadow/files/login.defs for the first
version of shadow in the tree (sys-apps/shadow-19990827-r1, committed on
2000-08-02).
So, I would conclude that Gentoo always used 1000 as minimum UID.
We could of course leave a gap for now, and allocate only 600..799.
This would leave the 500s for compatibility with very old systems.
It would have the additional advantage that we get an earlier warning
once the new range will be almost full. Even if we then allow IDs in the
60000s range, we presumably should keep some reserves of low IDs for
packages that really need them to be there.
