-To understand the utility of this, imagine a provider
-being mounted as a file system.
-Between the DEVFS geom's consumer and its provider we insert

-copy and consequently is transparent to the I/O requests
-on the path.
-We can now configure yet a mirror copy on the mirror geom,
-request a synchronization, and finally drop the first mirror
-copy.
-We have now, in essence, moved a mounted file system from one
-disk to another while it was being used.
-At this point the mirror geom can be deleted from the path
