Just the fact than /var/log/message contains lines as:
Feb 11 19:51:52 localhost acpid: client connected from 2074[0:0]
Feb 11 19:51:52 localhost acpid: 1 client rule loaded

etc...

Whereas my host name, set from HOSTNAME variable in 
/etc/sysconfig/network, is beria.inria.fr. I have to restart my syslog 
daemon to get it correct. So I guess just ensuring the hostname is 
either set prior the start of the logging process, or refreshing this 
last one thereafter, would avoid the issue.

I was probably wrong in seeing journald as a potential responsable here, 
tough, as it also happens on a mageia 2 system.
