I have no idea why this would be removed. I think it should be put back in.

restorecond and setfiles/restorecon should realize when they hit a hardlinked file with multiple labels and not label them.
I actually think the code should check every file and if it has hard links, not relabel the link until it finishes the search. Then check all the links and see if they all have the same label. Then set the label.
