This was discussed at some lenght in comp.sys.sun a while back, and to
summarize, the options I use for dump to make maximum use of a exabyte
tape drive is:

	/usr/etc/dump 0ucbsdf 56 5190 4100000 /dev/whatever file-system

Now it doesn't use the all the 2.3 Gigabyte of space, but it is close
enough for me not to worry about that.
