SunOS (later retconned
into 'Solaris 1') was BSD, while Solaris 2+ was System V Release 4. System
V R4 itself was the product of a grand Unix unification between Sun and
AT&T in which System V R3 picked up massive amounts of BSD features and
became much more BSD-like than before.</p>
<p>(System V before R4 was a very different place for BSD people. If I
remember right, there was no job control in the shell, people couldn't
be in multiple groups, and any number of other similar core differences.)</p>

It started of as a BSD derived system (not really a surprise given Bill Joy's affiliation with Berkeley), but then they replaced large swaths of code with what they got from AT&T - which was System V. This code eventually turned into Solaris. Check a Solaris 10 box and you'll find /usr/ucb with (ancient) BSD-compatible tools.</p>
