I'm not sure if you've been reading my Twitter posts recently, but I've been struggling for a while here to get our various Macs on campus here imaged. Originally, we had a lab full of Macs, and while NetBoot didn't work exactly as predicted, we could finesse it enough to get the job done.
Enter 2007, and not only do we have a lab full of different Macs, those original Macs now have to be reimaged for use elsewhere on the campus. The setup we were using on the Xserve refuses to boot any of the Macs, old or new.
...and don't even get me started on the whole Quark 7 thing!
It's all an exercise in frustration, all exasperated by the fact that all of this needs to be done around August 9th.
