Some years ago, you could write

| Requires: foo > 2.1

which would be fulfilled by foo=0:2.1 but not by foo=42:1.0.


Then, rpm was changed to interprete the statement above as

| Requires: foo > 0:2.1

So, program version 1.0 packaged with an epoch of '42' would be allowed.

Therefore, versioned requirements make sense in a special environment
only where you exactly know possible EVR values.
