No, I explicitly did that. (As I noted, there's a typo for that in the
example, as it uses "rw" not "r/w" , which doesn't work).

I've tried basically every variation of stage/nostage/ r/w / r/o at
different parts of the network, but the manager cmsd never seems to
actually consider the servers (even when I've already pre-staged the
file it's looking for by directly talking to the server xrootd service
and getting it to cache).
