mount done by root does not respect owner option
Last modified: 2007-04-18 12:42:45 EDT
Description of Problem: A mount done by root does not respect owner option. This is important for autofs support. (util-linux sources are not on the source iso images!) Version-Release number of selected component (if applicable): How Reproducible: Consider the line in /etc/fstab: /dev/hdd4 /mnt/zip100.0 auto noauto,owner 0 0 and ls -l /dev/hdd4 brw------- 1 achim disk 22, 68 Apr 11 16:25 /dev/hdd4 Steps to Reproduce: My shell: [achim@localhost achim]$ groups achim disk uucp here I mount the drive: [achim@localhost achim]$ mount /mnt/zip100.0/ [achim@localhost achim]$ mount|grep /dev/hdd /dev/hdd4 on /mnt/zip100.0 type vfat (rw,nosuid,nodev,user=achim) [achim@localhost achim]$ umount /mnt/zip100.0/ [achim@localhost achim]$ mount|grep /dev/hdd [achim@localhost achim]$ Actual Results: and now I do this as root: [root@localhost root]# mount /mnt/zip100.0/ [root@localhost root]# mount |grep /dev/hdd /dev/hdd4 on /mnt/zip100.0 type vfat (rw,nosuid,nodev) Expected Results: I'd like to have the owner flag respected even when I do this by root. Additional Information: This is the reason, why some howto-hints fail on Redhat Linux. In /etc/autofs.misc: zip -fstype=auto,owner :/dev/hdd4 [achim@localhost achim]$ ls -ld /misc/zip drwxr-xr-x 2 root root 16384 Jan 1 1970 /misc/zip this is not the intended result. The reason: mount is always executed as root by automount. The user=achim option does no apply by the same reason
Just because it doesn't list a specific 'user=' option there when you mount it as root doesn't mean its behaviour changes - if no user is explicitly authorized to umount it, only root can umount it. If you are wanting automount to do the mount as the user accessing the mount point, that is a different problem that is probably not practical to solve. Either way, NOTABUG.
