This behaviour is known and documented. http://www.freebsd.org/cgi/man.cgi?query=mount&apropos=0&sektion=0&manpath=FreeBSD+6.0-RELEASE+and+Ports&format=html After a successful mount, the permissions on the original mount point determine if .. is accessible from the mounted file system. The minimum permissions for the mount point for traversal across the mount point in both directions to be possible for all users is 0111 (execute for all). Nicolas -- http://www.rachinsky.de/nicolas
