Which version of systemd do you use? I tested the service file with systemd 29
and it works just fine:
michael ~ $ sudo systemctl start dnsmasq.service
michael ~ $ systemctl status dnsmasq.service
dnsmasq.service - A lightweight DHCP and caching DNS server
Loaded: loaded (/lib/systemd/system/dnsmasq.service)
Active: active (running) since Fri, 02 Sep 2011 16:25:45 +0200; 700ms
ago
Process: 28971 ExecStartPre=/usr/sbin/dnsmasq --test (code=exited,
status=0/SUCCESS)
Main PID: 28973 (dnsmasq)
CGroup: name=systemd:/system/dnsmasq.service
└ 28973 /usr/sbin/dnsmasq -k
Can you please do the following?
1) Run strace -o /tmp/strace.log -fF -tt -s2048 -p 1
2) Run systemctl start dnsmasq.service
3) Attach the (bzip2'ed) contents of /tmp/strace.log
That will allow us to better see what’s going on.
As for the functionality:
• The init script provides support for the ENABLED flag in
/etc/default/dnsmasq, which you don’t need when using systemd -- systemd
supports enable/disable: systemctl disable dnsmasq.service
• It runs dnsmasq as user 'dnsmasq' - I missed this one and we can easily add
it to the service file (User=dnsmasq in the [Service] section).
Simon, what do you think? Is running dnsmasq as user dnsmasq by default a
sensible decision?
• The resolvconf stuff I regard as obsolete when using NetworkManager or some
other configuration tool.
• LANG gets set if it is defined in /etc/default/locale. I’m not sure what the
effects of that are (I don’t set LANG on my system, I prefer the LC_*
settings). Does it somehow affect the behaviour of dnsmasq when resolving?
If so, how?
• As for configuration via flags (all these environment variables): In
general, the systemd way is to configure programs in their own configuration
files, so /etc/dnsmasq.conf is the place where all this should be configured.
Simon: Are there any options which are *only* available via command line and
*not* in /etc/dnsmasq.conf that are reasonable for users to change? If so,
which ones?
Did I miss any functionality?
Thanks for your bugreport, and hopefully we can improve the service file :).
Best regards,
Michael
