We've been through this N times before. You are mixing up two things:
testing or understanding problems with a new release and you deploying it.
You >should< be able to deploy and start servers from a new version
(technically) at SLAC without Andy. If there are problems, you back up to
the previous version and tell us what the problem was. He may be around
when you start new versions (it is >your< call when you start new versions),
but he shouldn't have to type any commands (or know all the machines being
used) to make it happen.
[This part of the discussion should probably be in the BaBar HN and
not the xrootd list as it is SLAC-specific.]
