Hi Roy,

Finally got around to working on this. Here is the hook I made on
to handle static IP:

/etc/dhcpcd.enter-hook/03-static:

# If interface is configured as static, don't run dhcpcd

if [ "$reason" = CARRIER -a -e "/etc/network/interfaces" ]; then
        # Search for a static entry
        if grep "iface $interface inet static" /etc/network/interfaces
        then
                syslog info "$interface is configured as static...exiting dhcpcd"
                dhcpcd -k $interface
        fi
fi

What do you think of this?

Thanks,
Amit
