I've just stumbled across TurnKey Linux, and it sounds great, but I have a basic question before getting deep into it. Is every appliance a full stack, including the OS, applications depended on, and the target application? For instance, I'm interested in MediaWiki. Do I install just the MediaWiki appliance, or do I need to install the LAMP appliance first? I see TurnKey Core is included in both appliances, so I assume each appliance is a full stack, but the MediaWiki appliance does not come out and say that. Thanks.
