	It would probably make sense to nuke fdlast from distinfo altogether.

	Thinking about it - sysinst should be able to tell when you hit the
	last disk:

	Suggestion (I):

	  Define a set of known disk sizes

	  When building sets:
	    - If its a single image and any of the known disk sizes, add a
	      null byte
	    - If the last disk in a set, and the same as the other disk
	      images, add a null byte

	  At install time:
	    - read the first disk image, if it is one of the known disk
	      sizes, remember it and prompt for the next.
	    - continue until you hit an image of a different size

	  This could cost an extra disk with a single null byte in some
	  very rare cases :)

	Suggestion (II):

	  Encode the number of disks in the filename:
	  eg: bas-aabh, bas-abbh, bas-acbh... bas-bhbh
