And don't underestimate the draw of a BSD that was "fixed", had mmap that
worked, unified page cache, VFS layer that was pleasant.  I worked for
Lachman before I worked for Sun, saw the guts of quite a few Unix OS's.
SunOS was by *far* the most pleasant and well thought out.  It was an
OS where you could predict what it would do based on the architecture
and sure enough, that's what it did.

I miss that source base.
