The CVS plugin is useful if you would like to track changes to your Bcfg2 repository using a CVS backend. Currently, it enables you to get revision information out of your repository for reporting purposes. Future plans are to commit changes to the repo which are made by the server.
Simply add “Cvs” to your plugins line in /etc/bcfg2.conf:
[server] plugins = Base,Bundler,Cfg,...,Cvs
