Comment 10 for bug 1432871

In order to solve this issue, I have written patches and got them integrated upstream.
gnulib commit: http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=commit;h=c6148bca89e9465fd6ba3a10d273ec4cb58c2dbe and
coreutils commit: http://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commit;h=3babaf83875ceac896c8dd3a64248e955dfecef9
have been authored by me.

While attempting to push these patches into Ubuntu, it became apparent that our version of coreutils does not contain the requisite patches to correctly support /proc/self/mountinfo gives more complete information than /proc/self/mounts which /etc/mtab now points to. Using /proc/self/mountinfo is the upstream way of doing things, and it allows us to resolve this specific bug.

Patches required in order to support /proc/self/mountinfo are.
