I think this is being grossly unfair and irrelevant; the information
provided was that NetBSD was a viable alternative which is correct.
All my modern machines run NetBSD and the only non supported hardware
is a 9 track magtape drive on a sun -- I don't consider that 
unreasonable as it's rather an unusal model.  I don't think PUPS
is the place for OS favouritism arguments, so please desist.

I don't feel that there is any need to be silly and pretentious
here; techinical arguments may be of interest, but `I'm right and
I know I am' arguments are just childish.

To add a constructive comment, there's been a lot written about the
history and tree of development of early unix up to the SYSV
and BSD split occured, but I'm pretty unsure about the rest.
It seems that BSD2 and BSD4 developed pretty much in parallel,
the former targetting the PDP and the latter the VAX;  Warren's
graphing data provide an interesting view of what happened,
but I'm unsure how closely related the two developments were
(especially in time of releases, introduction of new features
etc.).  I'd be grateful if someone more knowledgable could fill
in some of the details.
