Comment 2 for bug 904573

Dev builds now contain util-linux 2.20 and Linux 3.2, and I'm not sure which one fixed it (if either), but /etc/mtab is now being updated by mount again.

Still, after reading the technical arguments in http://bugs.debian.org/494001 it makes more sense to make it a symlink. The rcS code will still remain to intially build /etc/mtab, but only if it's not a symlink.
