Go nuts >(http://opensource.apple.com/source/objc4/objc4-680/). Make backups. YMMV. Heh. I see no mention of ARC in the release notes; is that not part of (supported in) the runtime? Still, is there a point in taking the risk? Not that it should be particularly hard to back out as long as you keep copies of the originals as well as a way to boot the system so you can mount the updated root and restore those original copies. I suppose that building with more than the standard optimisation settings will not make a significant difference in runtime performance? Are these supposed to be signed, btw?
