Hi,
since portreserve is constantly failing on my F16 systems, and based upon older and newer discussions on this topic, I wonder if it's still needed?!
Ask yourself....
1. Why were you using it?
2. Are you affected by its failure?
If the answer to #1 is "I don't know", then you don't need it.
If you have a different answer to #1 and your answer to #2 is "No", then you don't need it.
FWIW, I've never installed it nor needed it.
