You mean the installboot usage, or something else? Vax has had a
unified boot block on NetBSD ~forever. It was installed by newfs
earlier but now it needs installboot.

Vax only have one bootblock which is installed in the first 16 sectors

The boot block is the same for all different disk types. Which is nice :-)
Yes, indeed - but Jonny claims the conversion to this sheme broke
preparation of completely zeroed/new disks for 11/750 and others (but
not for micro vaxen, which is the only hardware I have).
VAX have everything needed to read UFS installed in the first 8k of disk
with the important asm stuff in block 0 and 1 on the disk, depending on HW.
All machines that have PROM-VMB + 11/750 and VAX8200 (with ROM routines)
For other machines the boot program is installed on the frontend media
(RX11, RL02 or something) so the boot blocks are never used.
