We also have a mixed Solaris/RHEL5 environment. Solaris reserves
UIDs and GIDS up to 99 for system purposes while the RHEL docs
claim that UIDs up to 999 are "generally reserved". However, we
had a Solaris environment in place where we started UID/GIDs at
300 when we began using RHEL and have not run into any issues
(except when an install of RHEL made the UIDs of avahi-autoipd
fall into the 1000+ range - outside of what even the RHEL docs
would allow) and overlapped with one of our NIS distributed
user's UID causing significant problems with their use of svn... ;-(
If you use a distributed scheme (NIS or LDAP, say) to keep all
user UIDs the same on all systems, there is no longer any special
gid to modify.
