Comment 10 for bug 989354

A vm versus a real machine should make no difference.

Mount looks at /etc/mtab, which in Ubuntu is a separate file,
not linked to /proc/mounts. The cgroup filesystems are mounted
with '-n' to not add entries to mtab.

It shows that there is something missing from /usr. Actually
I'm wondering whether /proc might be not yet available when
/sys is available, as that would explain it, but I wouldn't
think that would be done.

I just need to set up a new test machine and see what's going
on.
