Red Hat Enterprise MRG Grid assigns "64" to the "condor" user and group,
as documented in /usr/share/doc/setup-*/uidgid, so that's what I used for my
pools' condor accounts on Red Hat Enterprise Linux and CentOS when installing
UWM's HTCondor package.

Having the central account means that the RPM install doesn't try to
use an arbitrary UID and GID which might vary from system to system.

A number of the systems are also configured as diskless with NFS root
file systems so stuff owned by the "condor" user shows up on shared
directories and having the centrally-defined user insures that those
files will be recognizable anywhere.
