Regarding using the uname command as the basis for
system identification ...

As noted in
  http://www.opengroup.org/onlinepubs/009695399/utilities/uname.html
the uname command accepts the following options:
________________

-m Write the name of the hardware type on which the system
   is running to standard output.

-r Write the current release level of the operating system
   implementation.

-s Write the name of the implementation of the operating system.

-v Write the current version level of this release of the operating
   system implementation.

I have concerns that one OS installed on given hardware
might output a different 'hardware type' than a
different OS installed on identical hardware.

It's also worth noting that AIX 5.3 manpages indicate
     -r  Displays the release number of the operating system.
     -v  Displays the operating system version.
Thus,
    % uname -r
    3
    % uname -v
    5

Whereas on SunOS 5.9,
    % uname -r
    5.9
    % uname -v
    Generic_112233-11
