mount.cifs currently complains about the "comment" option: CIFS: Unknown mount option "comment=foo" mount(8) on Linux says: The command mount does not pass the mount options unbindable, runbindable, private, rprivate, slave, rslave, shared, rshared, auto, noauto, comment, x-*, loop, offset and sizelimit to the mount.<suffix> helpers. So if mount.cifs decides to re-read /etc/fstab it should ignore the comment option. A lot of online posts say to use comment=x-gvfs-show as an option to have a Linux file manager display a mountpoint for a user mountable filesystem. While the "comment=" part is superfluous when combined with an x-* option, the problem is still difficult to debug. Patch attached... peace & happiness, martin
