It should be smaller, faster, and sweeter than the Moo-Juice we rely on (DairyBox).
Ludum Dare doesn't run LAMP, however our current development VM DairyBox is a LAMP server (Linux+Apache+MySQL+PHP). This is a stub for when we finally create our own configuration that better mirrors what we run on the live servers.
If you wish to contribute to Ludum Dare, use DairyBox. JuiceBox is not supported at this time.
