[PATCH] Package dnsmasq init-file
If an already running DHCP-server is found on the configured interface, the init-script refuses to start, but does not give a hint why. It took us some days to track down this behavior in our MANET, where every wifi/adhoc-node runs it own DHCP-server. Now syslog is more verbose on this.
