Description:
The script I have placed in /etc/functions.d/auto_sudo does nothing else than

[[ $UID != 0 && "${0%/*}" == "/etc/rc.d" ]] && {
echo prefixing sudo automatically...
echo sudo "$0" "$@"
sudo "$0" "$@"
exit $?
}

Okay I admit I'm being very lazy here and and I'm aware the use of sudo has been repeatedly discouraged.
What happens, /etc/rc.d/net-tools sources /usr/lib/network/globals. There, the call to load_hooks does not preserve the argument list and leaves my portion of code useless, which is called by /etc/rc.d/functions and in turn by /usr/lib/network/globals/hooks/arch, the currently only hook.
Also it's strange, I don't know if those hooks are supposed to know about the action that's being taken, but I guess it could be important. Also I can't currently refer to examples pointed to by netcfg(8) manpage, since /usr/share/doc/netcfg{,contrib} doesn't seem to be packaged in [core].
Most other DAEMONS scripts source both /etc/rc.conf and /etc/rc.d/functions directly, and I thought of our daemon scripts being arch-specific, please correct me if I'm wrong.

Therefore I suggest to move the sourcing of /etc/rc.conf and /etc/rc.d/functions to lines 2 and 3 of the DAEMONS script /etc/rc.d/net-tool

Cheers!
