That's the "right" way of doing it. It's also probably possible to
use an in-core disklabel, i.e. have /etc/rc.local read in a disklabel
for the disk from the filesystem.

From the installation script, it looks like you want to add an entry
to /etc/disklabel:
dosdisk:\
:dt=ST506:ty=winchester:nc#CYL:nt#TRACKS:ns#SETORS:se#512:\
:pa#SIZE:oa#OFFSET:ta=4.2BSD:ba#8192:fa#1024:\
:pc#SIZE:oc#OFFSET
Where CYL, TRACKS, and SECTORS are the (translated) disk geometry
(number of cylinders, number of heads, number of sectors per track),
and SIZE and OFFSET are the size and offset of the NetBSD partition in
sectors.
Then:
disklabel -w -B /dev/wd0d dosdisk
