when using net-analyzer/smokeping: smokeping requires the fping binary to be set setuid root. if, for some reason, fping gets re-emerged smokeping stops working because the binary is no longer setuid root. a local use flag option on net-analyzer/fping should be added to set the binary setuid root. Reproducible: Always this could be considered a request for new feature, but for me it breaks smokeping and therefore considered a bug.
