Well, automated server pack does not mean you have to filter out client-only mods. Forge does that automatically. But I find it stupid to upload a server pack every time I update my modpack.All these mods could be simply downloaded from the manifest and archived into a zip and then automatically be provided as a server pack.
This would be hard to do unless A mod author or CF knows exactly what is a client mod an what is a server mod expecially if the author forgets to mark their client side mod as client side only etc.
You won't be notified about changes to this idea.
