Not really.  FreeBSD is open source and was way way behind SunOS.  That's
why so many Sun engineers were hugely butthurt when they were forced onto
a far inferior System V source base.  Scooter just didn't understand
how much polish had gone into SunOS 4.x.  It was a very talented group
of engineers, many of whom had no social life (he says looking in the
mirror :) so they poured all their energy into making SunOS great.

I'm biased because I worked there, but I've run code on all of the major
Unix offerings (AIX, IRIX, Ultrex, HP-UX and SunOS) and SunOS was hands
down a better experience, inside the kernel, as a user of the syscalls,
and in user space.  It's what a geeky engineer would want with the polish
needed to allow customers to have a good experience.

I think a free SunOS would have had a cult following.  I'd still be working
on it.  Sun's management just didn't realize what they were throwing away.

Whimper.
