Hi Thierry

Not sure what specifically you are looking for, but on a quick scan of
your policy:

I don't believe that you can /pipe/ inside an `execresult()' without
using a shell.

,----
| execresult("/usr/sbin/apache2ctl -M|grep ${liste_module_apache}","noshell");
`----

Also, I don't think it applies to apache modules since I don't think
there are any whose names contain invalid class characters (e.g. `-'),
but if you are creating classes from arbitrary strings, you should
`canonify()' when /checking/.

,----
| "MODULE APACHE ${liste_module_apache} pas présent"
|   if => canonify( ${liste_module_apache} );
`----

And finally, you must /quote/ a variable class expression, again, beware
if any `liste_module_apache' entry contains any characters that are not
valid in a class name, this won't work.

,----
| "module_${liste_module_apache}_nok"::
| "MODULE APACHE ${liste_module_apache} pas présent";
`----
