In this case they probably determined it unlikely that a user would want to hook an HFSPlus volume up to a RHEL server. They also disabled a whole bunch of 100Mbit ethernet drivers commonly found on older desktop motherboards in RHEL7 for the same reason.

I haven't had a chance to check things out yet, I'm still dealing with food poisoning I came down with after sending my question. :-( Maybe later this week. Al
