I just spent too many hours struggling with a newly created NetBoot Image that booted, but would not launch any applications from the dock & the item that was due to launch at login didn’t (Casper Imaging). However, if i logged out the NetBoot user & logged back in, all was well!
Come midnight (I was remotely NetBooting a machine), I decided to cut my losses & come in next day which was my day off.
Turns out the NetBoot was fine, the issue was simply that the iMac was building had a PC Keyboard connected & not a Mac one!!
As the tagline says, doing the donkey work to make you look like a smart ass!!
