Comment # 13 on bug 968042 from Patrick Schaaf

Created attachment 666881 [details]
systemd debug messages, for real now...

OMG, I'm stupid. Forgot that we have journald configured to not log debug
messages to the journal, but only to syslog.....

This attachment, corresponding to the situation described in the previous
comments (ending after I started postfix by hand), finally shows the full debug
messages (taken from syslog)...
