I was taught that hard links should generally be avoided unless performance demands because of the subtleties around modifying, copying, and moving hard linked files. In light of the replies I've gotten here, it doesn't seem like it can cause any trouble to use a hard link in this instance. It didn't trip up any of the package managers I've been looking at, for example. That's why I asked though. I appreciate you all taking the time to correct my misconceptions.
