Why was Solaris so much worse than SunOS?
Probably because it was so much more buggy on release and people were
more used to BSD and didn't like change and the fact that greedy Sun
had removed the compiler. Solaris 2.3 had core dumps from base
binaries everywhere where SunOS 4.1.3 seemed quite stable.
I think that the root cause is AT&T USL. When UNIX went from research
to "product" different people worked on it. And those people seemed to
lack the artistry, vision, and craftsmanship of the original developers.
AT&T pushed their SVR4 crud hard onto the rest of the world. Meanwhile,
the folks at Berkeley produced code more in the original tradition
possibly because of Ken taking a sabbatical year to teach there. SunOS
was the result of the pipeline between Berkeley and Sun.
Solaris was the result of Sun abandoning the Berkeley branch for the USL
branch.
