All good for OS X clients, but be sure you use that "Reboot Now" command after the automatic client update or forever hold your piece, i.e., you'll have to reboot them manually. As far as I can tell, you get one chance to do this "reboot now". OS 9 clients are not so lucky. There is no automatic update for those clients, and Software Update Control Panel tells me my software doesn't need updating for all but one of my OS 9 users so far. So I am locked out of clients that previously worked. Short shrift to OS 9 users, as usual. Even M$ has supported its older OS's for long after they've moved on. The archaic Windows NT *still* has updates, patches, etc. until later this year.
