Right idea, wrong version numbers.

SunOS 4.1 was the last major version of SunOS. It was BSD-derived and
very comfortable to those of us who grew up on VAXen. While SunOS 4
was still a current product, Sun came out with Solaris 2.1. It's
underlying operating system number was 5.1. Solaris 2.2 came out
as the "operating environment" that included "SunOS 5.2" and so on.

After Solaris had been around for a while, Sun retroactively named
SunOS to a Solaris 1 number. I don't recall the exact mapping, but
IIRC, Solaris 1.1.1 was also known as SunOS 4.1.3_u1, nearly the
last SunOS there was. I _think_ 4.1.4 was called Solaris 1.1.2, but
I am digging deep into memory.

As for Solaris itself, I never was compelled to use it until about 2.4
came out. There were apparently some radical internal differences
up to that point, requiring new third-party product reinstalles, etc.,
but I was not party to that. I really got my wings with Solaris 2.5.1
and 2.6. I'm running Solaris 8 at home (haven't bothered to go up
to 9 yet).

So... Solaris 1.x is the new name for SunOS 4.x and Solaris 2.x and up
are internally Solaris 5.x, etc.

Hope this clarifies things. If not, I'm sure there's a Solaris numbering
FAQ at or someplace similar.
