What is the difference between /dev/rst0 and /dev/rst8 on Suns?  Does one
have a higher storage capacity than the other when using tar or dump?

[[ The difference is very similar to the different between /dev/rmt0 and
/dev/rmt8.  0 is a "lower density" device, requiring more tape to fit the
same amount of information but less prone to bad spots on the media.  8 is
a "higher density" device.  For the rst device, 0 uses QIC-11 format and 8
uses QIC-24.  --wnl ]]
