Has anyone else noticed odd behavior with your Mavericks 10.9.x netboot image on newer Macs? Prior to Mavericks, my netboot images worked like a charm, while they took longer to boot since they're going over the network, they'd otherwise act more or less like a local installation.

However, I've been noticing that my Mavericks netboot images (I've made 10.9, 10.9.1, 10.9.2 and just today 10.9.3) are a little funny in that once the desktop comes up, just about every action has a HUGE delay before the action happens. This usually means a beach ball, but not always.

Also, sometimes the dock icons are "invisible". The space where they should be is occupied and when you hover the pointer you get the name of the icon, and clicking the space opens the app (after a long delay, I think it took a minute or more to open the image utility). Also, if you can manage to get a Finder window to open, icons are sporadically "invisible" here as well.

In addition, there's this weird system error box that sometimes shows up. It says "Unapproved caller. SecurityAgent may only be invoked by Apple software." I assume that's some sort of low level OSX security feature and something is trying to call a function that is not allowed by non-Apple software.
