Yes.  I liked it and have just made that change.  Thanks.
I also confirmed that Solaris5.9 still requires the

 has this bug.

I just got a complaint from one of the other CVS developers that Sun likes to see wither the uname output (SunOS 5.9) or their marketing name (Solaris 9) when referring to various versions of their operating systems.

I chose Solaris 9 and included a patch. I've also included Mark's SunOS=>Solaris mapping, for the edification of any interested parties.

"Solaris5.9" is a mistake in naming. It is mostly a Solaris branding
issue. What is in a name and a version number? Well, Sun seems to care
about Solaris versus SunOS branding...

Here is a mapping table for you to use.

      SunOS 2.x       == SunOS 2.x
      SunOS 3.x       == SunOS 3.x

Starting with 4.1.1B of SunOS we have the 'Solaris 1.0' release.

      SunOS 4.1.1B    == Solaris 1.0
      SunOS 4.1.2     == Solaris 1.0.1
      SunOS 4.1.3     == Solaris 1.1
      SunOS 4.1.3C    == Solaris 1.1C
      SunOS 4.1.3_U1  == Solaris 1.1.1
      SunOS 4.1.3_U1B == Solaris 1.1.1 B
      SunOS 4.1.4     == Solaris 1.1.2

The SunOS 5.x uname output maps to the Solaris 2.x numbers thru 2.6

      SunOS 5.0       == Solaris 2.0
      SunOS 5.1       == Solaris 2.1
      SunOS 5.2       == Solaris 2.2
      SunOS 5.3       == Solaris 2.3
      SunOS 5.4       == Solaris 2.4
      SunOS 5.5       == Solaris 2.5
      SunOS 5.5.1     == Solaris 2.5.1
      SunOS 5.6       == Solaris 2.6

After SunOS 5.6, they started number based on the second digit
      SunOS 5.7       == Solaris 7
      SunOS 5.8       == Solaris 8
      SunOS 5.9       == Solaris 9

Yes, it makes no sense, but Sun folks get huffy when you use their SunOS
uname output to map to their Solaris number incorrectly.
