Update ipaSudoRule objectClass on upgrades to add new attributes. Ensure uniqueness of sudoOrder in rules. The attributes sudoNotBefore and sudoNotAfter are being added to schema but not as Params. https://fedorahosted.org/freeipa/ticket/1314
The update files are sorted before being processed because there are cases where order matters (such as getting schema added first, creating parent entries, etc). 10 - 20: Schema 20 - 30: FDS Configuration, new indices 30 - 40: Structual elements of the DIT 40 - 50: Pre-loaded data
