+This approach only requires CVMFS and a valid Grid certificate or a user/host token in ```~/.globus```. It is the simplest approach for getting a CE up and running, but configuration is limited to the options given in the config files.

JobAgents will still run from CVMFS, but their startup script may now be modified - allowing for changes such as what variables are exported, scripts are run before start, and containers may also be enabled/disabled as desired. Other in-code overrides are also possible (at own risk). As with the first option, a valid Grid certificate or a user/host token in ```~/.globus``` is required.
