Daemons explicitly binding to an external IP may fail to start during system
bootup. The problem is the 'net' dependency being fulfilled by
/etc/init.d/netif.lo, which only sets up loopback networking. Instead, the
'net' dependency should only be fulfilled when all netif.* scripts have been
started, at least when rc_depend_strict is set to 'YES'.

This actually happened with maradns on my server, which binds to the external
IP explicitly and according do /var/log/rc.log got started before netif.eth0.
