Creating a domain controller and no auto-reboot

I'm using the xActiveDirectory DSC resource kit and the xAdDomain to setup my DC like this:

xADDomain FirstDS {
			DomainName = $DomainName
			DomainAdministratorCredential = $AdministratorCred
			SafemodeAdministratorPassword = $AdministratorCred
			DnsDelegationCredential = $AdministratorCred
			DependsOn = "[WindowsFeature]ADDSInstall"
		}

The problem is as it's going through, it won't reboot. I want it to reboot as many times as it once to get the bits installed and the server promoted.

Here's the output I get when it runs.

VERBOSE: [MYDC]:                            [[xADDomain]FirstDS] Target Machine is not running AD WS, and hence is not a domain controller

It was my understanding that if I just had the "RebootNodeIfNeeded" option set in the LCM it would auto-reboot and be happy. What am I missing?

Here's my LCM configuration:
