The history of Solaris
A while ago, Philip Pokorny explained to me what was up with Solaris (SunOS) version numbers. It's worth keeping as a reference.
In case you were looking for a longer history, check out this excerpt from the Solaris 8 System Administrator Guide.
Sun's operating system was originally based on BSD and called SunOS.
Numbered 4.x in line with the BSD numbering convention.
When Sun started working with AT&T and switched to the SysV code base, they renamed their OS Solaris.
In a fit of marketing confusion, they decided to rename SunOS 4.3 ->
Solaris 1.0. The new AT&T code base was called Solaris 2.0 but uname
reports it as 5.0 so that scripts that compared uname versions would see
that Solaris 2 was newer (5 > 4) than SunOS 4.
Solaris version 2.0, 2.1, 2.2, 2.3, were all generally pretty bad. 2.4
was the first Solaris release that was stable enough for my previous
employer to use. 2.5 was much better and 2.5.1 was rock solid.
Solaris 2.6 was pretty good, but major changes were coming.
With Solaris 2.7, the marketting types got involved again and renamed
the OS. They decided they couldn't compete with Red Hat 6 and Windows
NT 4.1 with a name like Solaris 2.7 so they renamed it "Solaris 7", but
uname *still* says 5.7.
The tradition continues with Solaris 8 (uname -> 5.8)
