I finally figured it out.
You can't call hostname during the post install to populate the
hostname. But by not calling hostname, you get the correct name inside
/etc/sysconfig/network.
Which then creates a different problem, I used to call hostname and
create a new name for the Myrinet interface. I will have to find a way
to be able to pull that info from somewhere else.
