To support our efforts to make Pantheon and all it's parts available on multiple operating systems and virtual private servers, we're implementing BCFG2 (http://trac.mcs.anl.gov/projects/bcfg2) for configuration and management. We've placed BCFG2 configuration files for Mercury on Ubuntu Jaunty 32 bit server in our launchpad project (https://launchpad.net/projectmercury) for folks to start using.
Note: we're working with the BCFG2 developers on a bug that causes libgd2-noxpm and libgd2-xpm to alternately install/de-install. Until this bug is addressed and released, don't use our BCFG2 configuration files for production servers.
As always, please feel free to submit your questions/suggestions!
