	1)	Use of partition c means using the entire drive as a swap space, so
		'access to other partitions' is irrelevant.  I do this routinely 
		on dataless Sun 3/80's (root file system, page/swap reside locally) 
		to make use of the 2nd 104MB hard disk, as we have up to 32MB memory
		on these systems, whose primary application is a memory pig.
	
	2)	As to use of partition a: as a swap space, I include the following
		/etc/fstab off one of our Ultrix systems: (VAX 11/780 w/2 x RA81):

		/dev/ra0a:/:rw:1:1:ufs::
		/dev/ra1a::sw:0:1:ufs::
		/dev/ra1b:/tmp:rw:0:4:ufs::
		/dev/ra1g:/src:ro:0:2:ufs::
		/dev/ra0g:/var:rw:0:2:ufs::
		/dev/ra0h:/usr:rw:1:3:ufs::
		/dev/ra1h:/usr/users:rw:1:3:ufs::

		As I recall this was done when that system was first upgraded to
		run Ultrix 2.0; it has been used successfully ever since.
