The manual *does* say that to access variables that aren't in a global (common)
scope need to be qualified:
http://www.cfengine.org/manuals/cf3-3.0.4.html#Variable-expansion-in-cfengine-3
and repeats this in other places, e.g.
http://www.cfengine.org/manuals/cf3-3.0.4.html#site_002ecf
http://www.cfengine.org/manuals/cf3-3.0.4.html#expand_005fscalars-in-insert_005flines
Granted, it doesn't explicitly say "this also applies to modules", however I
think
it's fair to point out that the manual does say:
Modules define variables in cf-agent by outputting strings of the form
=variablename=value
These variables end up in a context which has the same name as the module.
When the $(allclasses) variable becomes too large to manipulate conveniently,
you can access the complete list of currently defined classes in the file
/var/cfengine/state/allclasses. (my emphasis).
In this case, the information is there, it's in an obvious place, and it's
accurate.
I definitely agree that the manual has some shortcomings, but not this time.
Cheers
Mike
