Many Steam games support the steam workshop. It is an easy way to share community maps and addons and is very useful for custom servers, without needing to worry about setting up FastDL. LinuxGSM adds workshop pre-configuration to game server scripts as when available.
You will need a Steam API key, a collection to subscribe to (you can create one), and some config parameters in your LinuxGSM config.

For KF2 Server using LinuxGSM, workshop content is added in
