Description:
After upgrade util-linux-ng package to util-linux version 2.19-3 from testing, all FUSE filesystem no longer show up on /etc/mtab after mount, making it impossible to umount them.

Downgrade util-linux package back to util-linux-ng version 2.19-4 from Core fix the problem.

Note that this bug seems to affects all FUSE file system. Both unionfs, which are written in C, and my experimental FUSE file system written in Python are both affected.

Additional info:
* package version(s)
- util-linux 2.19-3

* config and/or log files etc.
- None

Steps to reproduce:
1. Upgrade to util-linux version 2.19-3 from testing
2. Mount a FUSE file system. Notice that even though the file system is working fine, it doesn't show up on /etc/mtab
3. Attempt to unmount the file system, cannot do so because it wasn't listed on /etc/mtab
4. Downgrade to util-linux-ng, mount the FUSE file system again and note that it show up just fine in /etc/mtab
This task depends upon

I've received a suggestion from mailing list (source: http://mailman.archlinux.org/pipermail/arch-general/2011-February/018687.html) to symlink /etc/mtab to /proc/self/mounts. I've tried it and it work. Now when I mount FUSE file system it show up just fine in /etc/mtab and I can now unmount it.
