    If this is your first install, automatically load on login with:
        mkdir -p ~/Library/LaunchAgents
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    If this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Or start it manually:
        mongod run --config #{prefix}/mongod.conf

    The launchctl plist above expects the config file to be at #{etc}/mongod.conf.
    If this is a first install, you can copy one from #{prefix}/mongod.conf:
        cp #{prefix}/mongod.conf #{etc}/mongod.conf
