:-) We should at least add a referecne to ast. However, there is no
ast man page.

OK.
: wst and ast are weird names. Doesn't the "s" in them stand for "SCSI"
: and not "streaming", so wst is the so-called-Winchester (non-SCSI) SCSI
: tape driver, etc? For completeness, we should have had nrrrwsst (the
: non-rewinding rewinding raw so-called-Winchester streaming SCSI tape
: driver) ;-). Seriously, why aren't there "n" and "e" forms of ast?
IIRC, The s in st is streaming. Since there was only one streaming
tape driver, it wasn't called sst and the name came over from SunOS
(but there may be a more direct path via the BSD trees). However,
this argument is weak because sd was the scsi disk and not the
streaming disk.
I don't know why there aren't n forms. There are on my system, but I
crated the devices by hand based on the st entries that I had when I
was beta testing Soren's wst driver (later recreated them for the ast
driver).
