Rudder

After upgrading rudder-agent through rudder-agent, the dpkg state is not correct:

# dpkg -l |grep rudd
iF  rudder-agent                         2.6.2-precise0               Configuration management and audit tool - agent

Looking into the rudder-agent output, shows this:

Q:env DEBIAN_FRONTEND= ...:cp: cannot create regular file `/var/rudder/cfengine-community/bin/cf-agent': Text file busy

Proposal:

Would it be a good idea to don't upgrade rudder-agent with the standard technique package management techniques, but as an option in rudder itself? As in: an "upgrade rudder agents" button somewhere, with tick boxes to in-/exclude nodes.
