Rudder

I tried to add a technique with the name "user home", which was interpreted in cfengine as "user_home" which is the name of an already existing GM.
The message was not that much explicit and I think it should explicitly tell that the technique name is already in use in Rudder.

An Error occured! Could not write technique 'user_home' from path /var/rudder/configuration-repository/ncf, cause is: Error while running post-hook command /var/rudder/configuration-repository/ncf/ncf-hooks.d/post.write_technique.50_rudderify.sh /var/rudder/configuration-repository/ncf user_home
