Description

If I use a technique using package_state on a 3.1 agent, i get the following error on the node:

# /var/rudder/cfengine-community/bin/cf-promises
/var/rudder/cfengine-community/inputs/Test_technique/1.0/Test_technique.cf:15:0: error: Undefined bundle package_state with type usebundle

Node is not working anymore then

We could:
  • create dummy generic method with opposite loading conditions, that would only report error
  • generate them automatically
  • detect that the technique depend on an unavailable generic method, and skip it

or something else more clever

Benoit, what do you think of this ?
