Yes, there might be *some* advantages to expect ;-) > In my laptop and desktop, I could only use journald, but since > systemd can be used along with rsyslog/syslog-ng, I still run > rsyslog: > > # systemctl status rsyslog.service rsyslog.service - System Logging > Service Loaded: loaded (/usr/lib/systemd/system/rsyslog.service; > enabled) Active: active (running) since Thu, 12 Jul 2012 21:39:04 > -0500; 1 weeks and 3 days ago Main PID: 388 (rsyslogd) CGroup: > name=systemd:/system/rsyslog.service └ 388 /usr/sbin/rsyslogd -n -c5 > > The reason is only that I actually like to keep my logs, even if for > a laptop/desktop is most of the times not necessary. Keeping journald-logs just needs "mkdir -p /var/log/journal" (and in case defining the size limit in the configfile). > I think the only thing I did to set rsyslog as my logger service was > to link the syslog.service file to it: > > # ll /etc/systemd/system/syslog.service lrwxrwxrwx 1 root root 39 > Jan 18 2012 /etc/systemd/system/syslog.service -> > /usr/lib/systemd/system/rsyslog.service > > For my servers journald is cute, but I would never think about > removing a "real" logger. For my servers I don't think about removing a "real" init-system ;-) No joke: in production environments I don't think of using systemd yet. Just playing around here and learning things. I would consider using it if it were officially supported by gentoo in terms of "you get a set of fully tested unit-files" etc ... but right now it always feels like "ah, there might be another howto" ... "maybe I lack some really important service" ... at least this is my feeling right now. learning. > So, in short: for servers install a real logger (I recommend rsyslog, > although syslog-ng should also work), never tried rsyslog, could have a look, yes. > and for laptop/desktop you > *could* do just with journald, but if it makes you feel better (as it > does in my case) you can also install a real logger. > > Now that I think about it, I haven't really looked at my logs neither > in my laptop nor desktop in months.

I also don't expect much difference in performance. There isn't that much to log on a desktop, and the load isn't that high most of the time. Thanks, Stefan
