Arch Linux

Description:

I got a warning from systemd each time shorewall starts :

févr. 06 11:58:33 Belette-PC systemd[1]: /usr/lib/systemd/system/shorewall.service:16: Standard output type syslog is obsolete, automatically updating to journal. Please update your unit file, and consider removing the setting altogether.

Additional info:
Versions :
* local/shorewall 5.2.8-1
* local/shorewall-core 5.2.8-1

Service file (/usr/lib/systemd/system/shorewall.service) :

I think the following settings should be used by default :
/etc/shorewall.conf :
LOGFILE=systemd
/etc/systemd/system/basic.target.wants/shorewall.service :
No StandardOutput setting

Maybe that would mean patching the example configurations in /usr/share/doc/shorewall/Samples/ as well ?
