Post build installs – seem to hang on restart command

I've been using post build installs kicked off by launch daemons. In my first post build script I set many of the standard first boot defaults. In my second, I install a handful of apps - and have a reboot command in place, but the reboot never takes place. I see a message in console that states that console couldn't detach - is this my issue? What should I be looking for? Kinda flying blind here... Thanks all, Matt
