How can unshare help? Perhaps you mean setns() + umount? But there can be
other processes in the same mnt ns which need this mountpoint?

But the main question is why we can't add a cli option for that? And the
patch is really simple after cleanups I sent. Hopefully I'll send it today
if I have a bit of time.

Oleg.
