dynamis class creation

[Bob Van Cleef]

This has got to be an FAQ, but I can't find it anywhere.

I want to define a custom class based on the level of OS.  So,
I wrote a simple little script that checks /etc/redhat-release
and returns rh60 for red hat 6.0 and rh6.2 for red hat 6.2 
systems, etc.  Now, the question is, "How to use that script to
define a corresponding class?

It appears that can create a separate line for each class:
        rh60 = ( "script that returns non-null only on 6.0 system" )
        rh62 = ( "script that returns non-null only on 6.2 system" )
which seems counter intuitive.

but there does not appear to be a method for having a script
that returns the name of the class that you want to define.

        define = ( "script returns name of class that is defined )

There are enough differences between various versions of Red Hat that
this has become critical.  (Three different "amd" configuration files
for one example.)  The standard classes include the kernel level, but
not the OS distribution level.
