On linux the net-tools suite of utilities has been long since deprecated. The relevant code that gets executed on Fedora and EPEL should be identified and patched out, with a suitable pull request upstream, to remove the dependency on any tool in the net-tools package and instead use suitable tools form iproute2.
The use of net-tools has been deprecated with the new release: https://github.com/rackerlabs/recap/releases/tag/1.2.0
