FWIW, RH7.2 the link is to /dev/sda(#), assuming no other scsi devices
present on the system.

"issues" for sure. Not the least of which is simple
documentation. Although enourmous progress has been and continues to be
made, documentation remains a challenge all through Linux and the
community. Part of the challenge, of course, is the sheer _volume_ of
stuff to be written up, indexed, cross-checked, food processed,
comprehended, and occasionally digested. Which is part of the reason I so
much appreciate ALE and other LUGs; members so often already know the
answer to the question I'm having trouble understanding.

Thanks to one and all.
