Note that the mountlist manipulations are somewhat fragile, and not very pretty. The reason for this is to avoid changing vfs_mountroot(), which is (obviously) rather mission-critical, but not very well documented, and thus hard to test properly. It might be possible to rework it to use its own simple root mount mechanism instead of vfs_mountroot().
