OK, I see ... thanks Andy, Lukasz.
The use-case I was testing this for comes from the UC-Grid and Pacific Research
Platform projects where the plan is that every member organization exports work
areas of local researchers through xrootd and this then gets accessible on every
other site (optionally through caching proxies). People can then send the
results back through xrootd to their local system ... so being able to manage
the space both as a local user or through xrootd is the key to making this work.
Being able to configure the server to ignore ownership mask from the client for
directory / file creation would allow us to do that with posix acls. I guess it
should be an oss option.
Andy, do you think this makes sense?
