Rudder

We want to be able to save configuration rules to the files system, accordingly to http://www.rudder-project.org/foswiki/Development/Pi_cr_group_export_import.

That means:

• add a sub-menu in administration screen for "Import / export policies"
• add a button to export (archive ?) configuration rules
• when the button is clicked, the content of /var/rudder/configuration-repository/configuration-rules is updated to the new configuration rules:
  • remove all existing configuration rules
  • add new ones
  • git add "configuration-rules" and commit

The last step raises interesting mutex question with other part of the git repository: what happens if the user request (in the OS) a git commit just after all cr were removed ? Not to grave if then, they are added back, but there is certainly interesting race conditions hiding in the mix.
