You're probably on an NFS filesystem with root squash turned on - the
output and error files are created by the condor_schedd, which is running
as root and then switches EUID to be user 'jeremy' as needed - but if
the Real UID == 0, then it gets mapped to 'nobody'.

The reason fib.log gets created is that condor_submit creates it - which
is running with RUID=EUID='jeremy', so there's no trouble in creating it.
