Well, for my own anecdotal evidence: My Rx is strong enough that my glasses pull my eyes inward a bit, and when I wear contacts, my main complaint is that my eyes look a bit too far apart. So in that case getting lasik and wearing glasses without an Rx would probably still result in that still being the case.

I don’t know about dnf, but pacman doesn’t do this by default. The only way to hold back packages is by writing it in the configuration.
