Well, I do that.  I have many classes defined in that section based on the
hostname. And that's somewhat my problem.  Those definitions use the real
server name - because the same cfengine script will be used when the server is
being setup (not under it's real name) and when it's in production (using it's
real name).

What I was trying to define in the control section was my own version of the
special variables.

Since the docs seem to warn not to do this because the special variables
aren't case sensitive, I thought I might get away with intentionally doing it
for my purposes.

I tried this but unfortunately --no-hard-classes removes too much.  And, even
if I use -Dclassname to define the real hostname as a class, that doesn't help
where I use the variables $(host), $(ipaddress), etc.
