I did not mark the parition type to FD so apparently the kernel or mdadm just executes and looks in the ndadm.conf file. When trying to start the raid manually, I found that the raid would fail unless I passed the partion assignments on the commandline to mdadm. However, when the DEVICE and ARRAY are defined in the mdadm.conf, the partion info was not required, just the device name, "/dev/md0". So, I think the raid failed to start at boot due to not enough information being available for it to startup, thus the mdadm.conf file being required.
