I wanted to share with everyone a problem I have been seeing and would like to know if anyone else has encountered it.
I have had consistent failures when attempting to create a netboot set from the latest fully patched version of 10.6.8. After creating the netboot set and booting a computer to it the process would halt and the screen would display a "do not enter" sign (a circle with a diagonal line through it). According to Apple's error descriptions this means that the computer can not load the netboot image.
I made close to 20 attempts at creating a working netboot set from 10.6.8, each time testing different image creation methods (fully Apple workflow, Casper Netinstall Creator, a mix of the two, etc.) and each time I had the same problem. I tried creating netboot images from two different computers and neither worked. I should point out that I used the same hardware to create a 10.6.8 netboot set in December. I can only assume that some update released since December has caused this issue.
The problem was not with the Netboot server- I tried it on two different ones and did packet traces that showed that the boot process was working. I could also use older 10.6.8 netboot sets without a hitch.
After failing to create a new 10.6.8 netboot set I used my normal procedure (https://jamfnation.jamfsoftware.com/article.html?id=63) to create a Lion netboot set and it worked perfectly.
Of course with the Lion netboot set I no longer require 10.6.8 netboot images but I was curious to see if I was the only one to run up against this problem.
