I just tested it and my setup to include the proper config files for different
clusters does not work anymore. Here is a reduced examples. The class
LISA_CLUSTER is defined by init_node and now the
cluster_name is unresolved: /var/cfengine/bin/cf-agent -KI -f
./test_promise.cf -DRUN
{{{
error: Unresolved variable '$(cluster_name)/cluster.cf' in input list,
cannot parse

R: run_test
