Last change on this file since 21abaef was 21abaef, checked in by Christian Mauderer <Christian.Mauderer@…>, on 07/15/16 at 05:32:56

freebsd: Don't use new wrappers for old ports.

Some of the commands have been adapted manually. So the wrapper
currently don't necessarily work as expected. For example ifconfig calls
malloc outside of the program call.

Property mode set to 100644
