Very good. This removes my biggest worry.

That's the functionality I definitely want to preserve - particularly with root-hopping, you very quickly end up in scenarios where /etc/mtab just becomes a weird mess. Without /proc/mounts, you're lost.

Okay, let's drop this idea then. The only use would be to access a not-yet-unmounted old root file system. But as you've pointed out, the security implications are messy at best.

I want this to keep things human-understandable. Without it, you can easily end up with half a dozen file systems claiming to be mounted on /. Also, for consistency, fuser should make use of this information in the future.

I guess I fixed this by accident ;-)
