I only skimmed this thread but thought I saw something about a socket being disabled with systemctl, and if it was the systemd-journald.socket well then that'd be a reason why rsyslog isn't getting messages. But I'm not sure what all Balint has changed from the Fedora 20 defaults, but my test VM is pristine so either Balint has changed something I haven't changed and he hasn't changed it back to the default. Or maybe he's run into a bug where he changed something, changed it back but it's not taking. Or other… My test was strictly two things. The first was: 1. dnf install rsyslog ###because it's not installed by default 2. edited journald.conf changing Storage=auto to none 3. Reboot There is no persistence at all in either /run/log/journal or /var/log/journal, yet there are entries in both journalctl and /var/log/messages, and the logger command inserts whatever I type after it into both. And the other test following this was: 4. change journald.conf Storage=auto again, i.e. back to default. 5. delete /var/log/journal 6. reboot And now I get a journal stored in /run/log/journal; from prior testing a while ago this is the same behavior I get when Storage=volatile I didn't extensively test the difference between Storage=none and Storage=auto or volatile (with /run/log/journal and /var/log/journal deleted). And I can't really tell from the documentation or the resulting logs; but I'm going to guess that none means it's using some limited amount of RAM (?) whereas =auto or volatile using /run/log/journal is on tmpfs and after it uses up the <handwaive> 50% RAM limit it starts to swap to disk. In either case they're toast at the next reboot.
