Red Hat Satellite - 5.7 - Kickstart hangs on running post installation scripts

After I upgraded from Satellite 5.6 to 5.7, I was unable to kickstart any new servers using my existing kickstart scripts.  The kickstart would start, do all my partitioning and package installation and then hang on "Running post installation scripts."  I let it sit for over 30 minutes, no go.

It did not register to my Satellite server yet, so I knew it had not processed the entire kickstart file yet.  I started making a new kickstart profile to see if it was something that didn't convert well in the upgrade.  When I got to the scripts part, I saw a new post script listed called "Registration and server actions"

I could not do anything to the script besides reorder. I reordered the scripts so that the weird script was on the bottom, updated the profile and tried to kickstart again. This time, it worked.

TLDR: Put the "Registration and server actions" post script on the bottom of your kickstart script listing.
