Re: special feature or dark area?? hostname's hyphen character brings inconsistency in cfengine

[Mark . Burgess]

Hyphens cannot be used in class names, just as they cannot be used in
variable names in any language I know of. Underscores can be used so you
must have a different problem. I am guessing that your class definition
is parsed after your rule to echo a string. 

This all works fine, it is used all the time for internal stuff.
