We don't yet have the symlink, until we do we should use "-n" here.

I'm planning to look into the remaining downsides of using libmount
and symlinking mtab to /proc/self/monuts, to see if we can make the
switch. "The others" are doing it, so hopefully we can join soon. If
anyone knows of problems, I'd be interested to know.

Cheers,
