Rudder

Somohow, I have two dsc-common technique in my ative technique tree:

It may be related to an upgrade of the DSC plugin...

I had the same problem on a fresh install of rudder and plugin.

1. add techniques in /var/rudder/configuration-repository/techniques
2. schedule a reload of the technique tree at next webapp restart
3. restart the webapp
4. the webapp reloads the techniques, create the ActiveTechnique
5. the plugin adds the ative techniques
