No, I think it's correct

'man ktrace'
basically:
ktrace -i chio-scsi -check (or whatever option is was)
will write a ktrace.out file. You can read it with kdump.

It's possible. If so it's not hard to correct :)

If you can use chio and tar to write to a tape then it should be OK.

Or compile it from pkgsrc (http://www.netbsd.org/Documentation/software/)
It's possible that this can change a few things, as there are some patches
in pkgsrc/sysutils/amanda-server
But the prebuilt package should work.
