[Commotion-admin] [commotion-router] dnsmasq networking error breaks interfaces (#95)

[Ben West]

One of the freifunk packages inserted this cronjob upon install to
periodically restart dnsmasq with SIGHUP due to an apparent problem with
dnsmasq crashing.  (Not sure if the balky version of dnsmasq that prompted
this cronjob in the first place has since been replaced with a newer/fixed
version.)

5 * * * *    killall -HUP dnsmasq

Does this fashion of restarting dnsmasq help with the problem you're
describing?
