Well, you applied the third patch in the series of six anyway, :) so the mention of those [u]helper markers was removed. I'll submit a patch later to restore them, worded more clearly. But first let's make sure that I understand what they mean. First there was commit f19c952b2fc07ddd7a698cf3a213a9a16d13e7ba "umount: use helper= for all UIDs", where 'phelper' is renamed to 'helper', because it serves not just for root. But two weeks earlier there was commit c56226697342ddd663492f77768e7a7cb8e579a1 "umount: call /sbin/umount.<uhelper> for root user too". So, if I understand well, uhelper= and helper= would behave exactly the same under all circumstances? $ udisks --mount /dev/sda3 Mounted /org/freedesktop/UDisks/devices/sda3 at /media/Mint Petra $ grep sda3 /etc/mtab /dev/sda3 /media/Mint\040Petra ext4 rw,nosuid,nodev,uhelper=udisks 0 0 $ ./umount -v /dev/sda3 (Oh, that last command is surprising: it doesn't say anything. I would expect it to say that /dev/sda3 was successfully unmounted. Oh, and why isn't sda3 'noexec' here although it was mounted by a user?) So when using udisks, a uhelper= marker will be put into the /etc/mtab file (the real one). Is there any program that will put a helper= marker in the /etc/mtab file? (I call it a 'marker' because it is not a mount option: putting it in /etc/fstab makes no sense, and using it on the command line does not work). $ ./mount -o uhelper=udisks /dev/sda3 lt-mount: only root can use "--options" option $ sudo ./mount -o uhelper=udisks /dev/sda3 lt-mount: can't find /dev/sda3 in /etc/fstab Benno -- http://www.fastmail.fm - Choose from over 50 domains or use your own -- To unsubscribe from this list: send the line "unsubscribe util-linux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
