With the nitros9 /sh descriptor, you can even mount a .dsk image that 
been copied to disk as a file. There are at least as many ways to gain 
access to a .dsk image file as there are ways to skin a critter.

Using the normal os9 file system, determine the address of the file from 
its file descriptor, and using dmode, put that address in as the lsn0 of 
the disk image, into the starting offset in the descriptor.  Do a 
dir /sh to reload the buffer, and that image file becomes a normal disk, 
fully readable and writable.
