* Makefile (run-client): Add "--network-hook-dir" option.
* plugin-runner.c (main): Only try to work around Debian bug #633582
if started as root.
* plugins.d/mandos-client.c (run_network_hooks): Bug fix: Run all
network hooks, not
just the first one.
Also add debug output.
(main): Only try to work around Debian bug #633582 or run network
