Under SunOS/Solaris, this would normally be done using a loopback mount.
(Faster than NFS, maintains unix semantics, and doesn't open the security
hole of having an NFS server running...)

I see that the mount(8) man page references mount_lofs, but there is no
mount_lofs man page, nor is there an /sbin/mount_lofs.  Does anyone know
why loopback filesystem support seems to be missing from FreeBSD?
