/*! \brief mount

	\todo I'm using the B_GET_GEOMETRY ioctl() to find out where the end of the
	      partition is. This won't work for handling multi-session semantics correctly.
	      To support them correctly in R5 I need either:
	      - A way to get the proper info (best)
	      - To ignore trying to find anchor volume descriptor pointers at
	        locations N-256 and N. (acceptable, perhaps, but not really correct)
	      Either way we should address this problem properly for OBOS::R1.
	\todo Looks like B_GET_GEOMETRY doesn't work on non-device files (i.e.
	      disk images), so I need to use stat or something else for those
	      instances.
