@bentoms and other AutoCasperNBI users... I am having trouble figuring out how to solve this. Issue is when when applying a 10.11.1 image (15B42 created with autoDMG..no addl pkgs) and utilizing v1.3.0 of AutoCasperNBI. The process seems to kick off fine, runs for a while and write a fair amount of data ... but then after a while, the process halts with "Error: Generating Kernel cache"

I have looked through the logs...(snippet below)

Mon Nov 9 19:02:35 PST 2015 Error: Generating kernel cache

...I see the error, but I am not sure for what reason that the kernelcache kext couldn't be used/written. The NBI directory that is written is 10.26GB in size so there is certainly a payload. I am looking through the code:
https://github.com/macmule/AutoCasperNBI/blob/master/AutoCasperNBI/AutoCasperNBIAppDelegate.applescript

but I am not understanding where the problem is. This is the area of the code I was trying to look through, but I'm not exactly sure what I am looking for.

 -- Generate the Kernel cache

    on generateKernelCache_(sender)

        try

            ---- MAKE x86_64 FOLDER ----

            -- Update Build Process Window's Text Field

            set my buildProcessTextField to "Creating x84_64 folder"

            delay 0.1

            -- Update build Process ProgressBar

            set my buildProcessProgressBar to buildProcessProgressBar + 1



...

Anyone have any ideas or able to help me decipher what I'm looking at? I appreciate the help in advance!
