With the right license (BSD), I'd go so far as to saying there'd be no
BSD 4.4, or if there was, it would have been rebased from the SunOS
base... There were discussions between CSRG and Sun about Sun donating
it's reworked VM and VFS to Berkeley to replace the Mach VM that was
in there... Don't know the scope of these talks, or if they included
any of the dozens of other areas that Sun improved from its BSD 4.3
base... The talks fell apart over the value of the code, if the rumors
I've heard are correct.
