Which brings up another question:  what DVD writers are supported by 
NetBSD?  Although the drives are expensive, the disk themselves -- even 
the rewritable ones -- are cheap.  I know there's a debate about 
formats; it isn't at all clear to me if that matters for this sort of 
application.  What does matter is how one can write to the drive.  With 
cdrecord, I have to build a .iso image of the data I want to write.  
But that's quite suboptimal for use with dump/restore.  Has anyone 
tried that?
