Well, the SPARC Solaris 8 'fdisk' appears to work with SCSI disks, too.
Apparently an act of linuxation...

Yes.

format has an 'auto configure' mode. When I select that, it comes up with
reasonable drive data, but format:verify talks about a corrupt primary
label, and format:partition:print gives me a vanilla default layout.

If I know that Solaris cannot make any sense of a NetBSD label, I can
simply start the new installation by setting up Solaris first. That's the
point of planning and asking questions _before_ I go trashing my main
server.  ;)

Mhm. I used sunlabel to adjust the end of the 'c' partition so that it
equals that of the 'g' partition (both ending on cylinder boundary). If
this causes a re-write of the entire label, it has made no difference to
Solaris.

Mounting a Solaris UFS partition readonly in NetBSD, btw., only got me

/mnt: bad dir ino 2 at offset 0: mangled entry

'-- ick.'
