Yeah.  And, some of the older descriptions of how to do this required that.
But, since the bootloader can do this now, and is for others, I hope to
avoid that.

FMI, in your case, is the boot partition you put on your sparc normally
mounted, or just a small only-mounted-to-be-updated partition that only
ofwboot uses?  In either case, what files need to be in it?
