Looking at some of online documentation I see no means to either export the
hash variable pulled into the modules from hiera or to export the defines
called with "create_resources".
Is there a way to do something like @@$backuppc_db_dumps =
hiera('backuppc_db_dumps') ? Or possibly a way to export a custom define
with all the parameters passed to it?
Thanks
