Don't mess vars and classes and, perhaps, read the Cfengine reference
more thoroughly. Brief rules are:
1. Variables can be accessed outside a bundle by bundle name, e.g.
$(bundle_name.variable_name)
2. Lists cannot be accessed outside a bundle directly and should be
reinstated locally, e.g.
vars:
"local_list" slist => { @(outer.list) };
3. Classes only become global being defined either in common bundles
or in compound bodies, e.g.
bundle common foo
{
classes:
"global_class" or => { "any" };
}
bundle agent bar
{
files:
"/tmp/foo"
create => "true",
classes => if_repaired("foo_done");
}
# defined in cfengine_stdlib.cf
body classes if_repaired(x)
{
promise_repaired => { "$(x) };
}
