On the question posed by the Subject, please don't change any type
On a related question, please support the MBR_PTYPE and disklabel
formats from OpenBSD.
Likewise, support the MBR_TYPE and disklabel format for FreeBSD.
(I have several systems that I haven't upgraded from OpenBSD to NetBSD,
because they have a lot of data on a second drive that I cannot read
with NetBSD on the first drive. If NetBSD can support MSDOS and Linux,
it should be able to handle other *BSDs.)

1) systinst is primarily for installing a "new" system.
2) new systems will have new MBR numbers.
3) upgraders of old systems will be using the old-hand method
(mentioned below), and compiling their kernels the old way, and
thus can turn it on for the rare occasions it's needed.
4) what we really need is an fstab that recogizes the version flavors
of file systems, all at the same time. COMPAT_386BSD_MBRPART is
contrary to that expectation.
(OK, OK, I really do have the 25 diskettes for 386BSD 0.1 over there
under the desk, covered with dust, but I haven't tried to load them in
at least a decade.)

Me Too. I'm in favor eliminating the "upgrade" option from systinst,
and better documenting the steps for upgrading by hand. Especially now
that the "new" etcupdate is available (that systinst never even solved).
What does the "upgrade" option offer that would not be solved by
