question: why does the ULTRIX-32 (VAX) V3.1 cdevsw struct have eleven entries
per device while the generic Berkeley 4.3 have only ten? and when did this
extra entry appear and what is its purpose?
compare the /usr/src/sys/vax/conf.c on a Berkeley 4.3 system with the
/usr/sys/vax/conf.c on an ULTRIX-32 (VAX) V3.1 system. i called the digital
technical support people but they had no answer other than hinting that it
might be some future hook for V4.0. thanks.
