But it won't help if the mount calls into an external binary, like how nfs calls into /usr/bin/mount.nfs.  Each helper program would need to gain a --in-ns-of argument, and util-linux would have to pass it on.  So that's a next step here.

I think we have to work on turning off of the --mnt namespace. 
Basically just mount up the directory and run a process within the
chroot.  This would eliminate all of the problems we are seeing with mnt
namespace.
