Systemd journal log file setting

The new openSUSE 13.2 journald (from systemd) is sometimes quickly
using up disk space. 
 There are setting you can tweak in /etc/systemd/journald.conf 
 [Journal]
Compress=yes
SystemMaxUse=500M
SystemKeepFree=2G 
 After that, restart the services a few times for the
changes to take effect: 
 systemctl restart systemd-journald.service  
 systemctl restart systemd-journal-flush.service  
 You should see a reduction in the size of the /var/log/ directory
almost immediately.
