Replace restart with SIGHUP

spark404 · spark404 · commit c9c68e192835 · 2013-04-07T21:46:38.000+02:00
This signal will force the dnsmasq daemon to reload the configuration directly. This is much faster than restarting the daemon, which result in a much smaller window during which no dns server is available.

Tested by using the replaced version of edithosts.sh on a running vrouter causing dns problems.
