Title:
dnsmasq and resolvconf hangs on start
Status in dnsmasq package in Ubuntu:
Incomplete
Status in dnsmasq package in Debian:
New
Bug description:
I installed today dnsmasq and I use resolvconf in background.
Problem is, that systemd takes 1 minute or so after service start and
than reports:
root@proxy:~# service dnsmasq status

Loaded: loaded (/lib/systemd/system/dnsmasq.service; enabled; vendor

when I look into the start script /etc/init.d/dnsmasq there is a func
systemd-start-resolvconf which points to start-resolvconf.
There is this part:
for interface in $DNSMASQ_EXCEPT
do
[ $interface = lo ] && return
done
Before I had not defined DNSMASQ_EXCEPT in /etc/defaults/dnsmasq.
Problem is, that this part MUST be faulty! When I commend it out, I
can start dnsmasq! It looks like it loops forever there?!
Also if I define DNSMASQ_EXCEPT to my listen interface, it works - but
is is really needed?
I found a other user which had the same problem:
