Let's say I have mog.rpm with an rpmspec that defines the following Requires direction:
Requires: kupo >= 2.0
I know the Requires is enforced on rpm installation/upgrade. Is it enforced at any other time? For example, if kupo v2.0 has some regression and I downgrade it to kupo v1.9, will the Requires directive in mog.rpm prevent the downgrade? Or is that only enforced when changes (i.e. installation/upgrade/downgrade) are being made to mog.rpm?
Yes, it is enforced all the time.
