Unfortunately, the concept of a kernel-level current directory must be retained in Linux, otherwise things like a chroot jail would be impossible.

The new system call that splits off the pathname space for private mounts is probably a susperset of chroot(), and chroot() could be implemented on top of it. You don't need a current directory pointer for chroot() to work. Just a root.
