	Hello Peter,

	I beleive we asked how to do that at some point (hide
the path arranegement) except that we could not figure out on how
to mix /home and /data into a single substitution. Your case of
oss.localroot /kanga and oss.remoteroot /kanga or /xrootd at SLAC
ar a bit too convenient. Can we trick olb with soft-link or there
is a simple syntax which can take care of all /data + /home (the
path afterward is all and the same) ??
