NetBSD/i386 is my platform (think of it as FreeBSD only better :-)).
/dev/rst0 is the raw device, the n prefix version is the no-rewind version.

I am sure the author can explain the changerident field more. I think is
kind of like a quirk table where it maps the expected result from each scsi
command used by chg-scsi.

Changerident?  That name doesn't grep in the 
amanda-23.4.5p120051218/example dir where a sample chg-scsi.conf lives.

And I wonder how much diff there is between the 6 slot C1553 and the 4 
slot seagate 4586np.  Other than the seagate stacks the tapes 
vertically and from pix, it looks like the hp handles them horizontally 
somehow.

However, in the docs dir, there is a .txt file, chgscsi.txt, that does 
describe this, unforch this file was apparently added after I'd given 
up, its dated: May 13  2005 chgscsi.txt.  By then I'd bought a 200GB 
pata drive and partitioned it for /var, swap & 180GB as /amandatapes.  
I have 10GB of swap & haven't ever used more than 10 megs of it.  
Gigabyte of ram though.

Thats not a linux device name.  Solaris?
