Nice, but what's the point of having it kernel-dependent?
AFAIK, Condor is dependent on glibc versions (since standard universe
libs would replace it) and thus on Linux distros/versions

YOu really want to have transient data on AFS?
My guts tell me that there'd be better ideas...

Obviously there have been requests for AFS support, but if you read the
corresponding parts of section 3.3 in the manual (USE_AFS=...) you might
get the impression that it's no good for everything

AFS is powerful indeed, but
- standard universe doesn't rely on shared resources at all
- there's NFS

what's the point of using AFS for everything Condor? (It's probably OK
for the RELEASE_DIR, but everything else I would not put onto AFS. Try
to convert me.)

Sure... had a good laugh the first time...
