Some Uuid tweaks, not much, just figuring out the format. MyriadFs is coming
along quite nicely. It looks like it works great for normal programs, but there need to be some tweaks made to a few things before it's working 100% via fuse. Also, the fuse module won't let you specify a file, a little odd.
