SIU fails to create images

Question

Using SIU 10.6.7 on a machine updated to 10.6.8, trying to create a NetInstall image of a 10.6.3 Retail disc. SIU fails consistently, even after a reinstall of the server admin tools.
This is what I get from the console log:
12/8/11 1:12:37 PM          System Image Utility[154]          Assistant - Selected source:"NetInstall of OS X 10.6.3 Installer".
12/8/11 1:12:58 PM          [0x0-0x13013].com.apple.server.SystemImageUtility[154]          objc[154]: Class SIUDiskUtility is implemented in both /Applications/Server/System Image Utility.app/Contents/MacOS/System Image Utility and /Applications/Server/System Image Utility.app/Contents/Library/Automator/Define Image Source.action/Contents/MacOS/Define Image Source. One of the two will be used. Which one is undefined.
12/8/11 1:13:02 PM          System Image Utility[154]          Something didn't really work out here...
12/8/11 1:13:02 PM          System Image Utility[154]          Failed to create image from script createNetInstall.sh.

Answer 1

Try setting the debug level to verbose in the SIU preferences. This should give more information about the failure in the run log for the image build.
You should also be looking for the SIU logs instead of the console. They're in ~/Library/Logs (you access them through Console.app as well.)
I've never actually seen the "Something didn't really work out here..." message occur. It means that SIU failed to communicate with its helper tool that builds the images.
