If the directory before the mount has 0777 (all rwx), after the mount those will be the permissions for the root of the mounted volume.

This is a newly formatted ext4 volume.
So whilst it is mounted, change its permissions (i.e. chmod whatever /backup) and its owner if you wish. Then unmount it. Check again what the permissions of the mount point are. Then mount it again and check what the permissions of its top-level directory are again.
This did not seem to do as I expected on an ext4 partition: mount /backup cd /backup chmod a+rwx . After a remount, the permissions are not a+rw Sigh. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
