Okay, I must have missed something, here.

Just upgraded.  Root fs is ffsv2.  Why?  FIIK -- it seemed a good thing
to do.  It certainly seems to check/build faster than ffsv1, but that
could just be me.  In any case, root is now ffsv2, for better or for
worse.

installboot's semantics have changed mightily since the last time
I had need to run it, and the manpage is less than enlightening
since it doesn't indicate which secondary bootblock is required for,
e.g., ffsv2.

I ran:
	installboot /dev/rwd2a /usr/mdec/bootxx_ffsv2 /usr/mdec/biosboot

which ran, but now, when I boot, I get (forgive my faulty non-ECC memory):

  Invalid bootblock for fstype
	(or is it "invalid fstype for bootblock: ffsv2"?)

Something like that.  Anyway, the system is not bootable from that drive
and I have to manually intervene and reselect my boot device.

I'm going off to look through the archives again, but if there is
something simple I'm missing, clues would be appreciated.
