When using a combination of udhcpc and avahi-autoipd in case of receiving IP from a DHCP server, the following message can be seen: "Failed to kill daemon: No such file or directory". Add a check for a running avahi-autoipd to fix this issue. Signed-off-by: Lukasz Tekieli <tekieli.lukasz@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
