All the permission information, and even the bit denoting whether or not this inode refers to a directory is stored in the inode, and can easily be checked in such a call." The permission information is distributed throughout the path to the directory. If /usr/fred is mode 0700, then the fact that /usr/fred/sources is 0755 should not be construed as sufficient reason to allow another user to chdir to /usr/fred/sources. -=- Andrew Klossner (decvax!tektronix!orca!andrew) [UUCP] (orca!andrew.tektronix@csnet-relay) [ARPA]
