I don't see patches 4 and 5 so I don't know if you have covered this
elsewhere but a very important part of the reason for MS_NOUSER is to
prevent unmounting of rootfs.
The entire vfs breaks if you are allowed to unmount rootfs, and it
appears this patch is allowing that.
I mean I tried "mount --move / home". (--bind worked.)
