We use the mounts to share an initial folder with either rw or ro wrights in a user directory. The user directory is then accessible through a web interface, sftp, webdav and rsync. There is probably better ways to do that now but that's a legacy app (2009) that we'd rather leave alone :) > It's true this issue should be looked into, but it doesn't look urgent as > long as there are alternatives. Yes, not urgent and very specific. I'm going to try to set the mounts to private as Max suggested and see how it goes. Thanks for your help.
