I agree.  This is not a general disk formatting utility.  Furthermore,
it is a *sucky* interface to a disk formatting utility.

I'm sure Charles meant that this was a sucky interface for a disk
formatting utility, and not that it is a sucky interface for a
general "send an arbitrary CDB" to a SCSI device.  I took it to
be the second.  I know Charles monitors the FreeBSD lists, and
I assumed he knew what the utility was for.

A reading of Charles's posting shows it combines sarcasm ("careful
readers will notice") with strong criticism ("*sucky*") and that
my response showed me to be thin skinned and petulant.  So I think
I'm right about some parts of that last post.

Anyway, 'nough said.
