4.3BSD-Quasijarus will eventually. For now if you want to run the
4.3BSD-Quasijarus userland, run it atop of an Ultrix kernel. Will work

A warning for naive list readers. NetBSD's definition of "runs on" means that
you have to part with all of your mass storage devices and use the bare CPU as
diskless peering-at toy.

4.3BSD-Quasijarus will eventually run on nearly every VAX ever made? When will
this happen? To speed it up, subscribe to the Quasijarus mailing list and join
our team.

The fact that Ultrix originally started from 4.2 is absolutely irrelevant,
since when 4.3BSD came out, Ultrix fully caught up with it. As the principal
maintainer and software architect of 4.3BSD-*, I know this better than anyone
else, and I state authoritatively that the complete 4.3BSD-Quasijarus userland
will run perfectly atop of an Ultrix kernel.
