Subject: Mounts and namespaces

Hi,


what happens to mounts when the namespace they exist in, exits?
In my concrete case:

	./newns /bin/bash
	# clone(CLONE_NEWNS | CLONE_THREAD | CLONE_SIGHAND | CLONE_VM)
	# and exec to given program
	mount /dev/loop0 /mnt
	exit

Still mounted and unreachable forever? Forced unmount and fs corruption?


	Jan
