From 9e660acd6bd1fd00b0de733371cab81b693165b3 Mon Sep 17 00:00:00 2001 From: jow Date: Sun, 21 Nov 2010 13:53:27 +0000 Subject: [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.
