In Fedora 15 /etc/mtab will be a symlink to /proc/mounts by default, This will break using the crypt filesystem in /etc/mtab to get filesystems mounted by mount.crypt umounted by umount.crypt. But there is a uhelper mount option that can be used instead, therefore please add support for this:
http://lists.fedoraproject.org/pipermail/devel/2011-January/147993.html

According to the manpage of umount it should already work for F14.

# mount -o uhelper=test /dev/sda1 /mnt/test

Won't record the uhelper option anywhere (neither in /etc/mtab, nor /proc/self/mounts nor /proc/self/mountinfo).
util-linux 2.19-rc1, kernel 2.6.37.

I suggest that you take care of a patch, based upon the time left to F15, and since Fedora is the distro that wants to have an mtab symlink so badly :-)

Highprio since openSUSE 11.4 will ship with symlink too.

In Fedora 15 util-linux v2.19-rc1) (the uhelper option will be stored here: /dev/.mount/utab
I guess in previous versions it will be /etc/mtab,
I did not test anything this myself, yet.

Talked to Karel. util-linux 2.19-rc1+git does not yet support calling umount.crypt from umount with its new utab scheme from all user accounts.
