Or: grepcmd = ( "/bin/sh -c '/bin/egrep foo /whatever >/dev/null'" )
so I don't see "foo" from all the non-redhat systems.

Yeah... I guess that's probably the best way to work around it. I ended 
up not needing to do what I was trying to do, but in future it would be 
nice if cfengine would only do the thing on the right if the rule on 
the left is true. That's how it works outside the classes: section and 
it would be useful if classes: would operate the same way.

Anyway, thanks for the suggestion, Wil!
