1 Sun seems to care about Solaris versus SunOS branding...
3 Here is a mapping table that maps the `uname -sr` values to Sun's marketing
9 Starting with 4.1.1B of SunOS we have the 'Solaris 1.0' release.
11 SunOS 4.1.1B == Solaris 1.0
12 SunOS 4.1.2 == Solaris 1.0.1
13 SunOS 4.1.3 == Solaris 1.1
14 SunOS 4.1.3C == Solaris 1.1C
15 SunOS 4.1.3_U1 == Solaris 1.1.1
16 SunOS 4.1.3_U1B == Solaris 1.1.1 B
17 SunOS 4.1.4 == Solaris 1.1.2
19 The SunOS 5.x uname output maps to the Solaris 2.x numbers thru 2.6
21 SunOS 5.0 == Solaris 2.0
22 SunOS 5.1 == Solaris 2.1
23 SunOS 5.2 == Solaris 2.2
24 SunOS 5.3 == Solaris 2.3
25 SunOS 5.4 == Solaris 2.4
26 SunOS 5.5 == Solaris 2.5
27 SunOS 5.5.1 == Solaris 2.5.1
28 SunOS 5.6 == Solaris 2.6
30 After SunOS 5.6, they started number based on the second digit
32 SunOS 5.7 == Solaris 7
33 SunOS 5.8 == Solaris 8
34 SunOS 5.9 == Solaris 9
36 The common terminology is to use the name "SunOS ..." to designate SunOS 2.x,
37 3.x, 4.x, and "Solaris ..." to designate SunOS 5.x.
