[systemd-devel] Missing previous boot system journal

[Yun-Chih Chen]

I've explicitly enabled persistent storage in journald.conf.  However, it
seems that the system journal of previous boot is still missing; only some
user journal persisted.  Am I missing anything?  Thanks in advance.

I'm running on Archlinux with Linux 4.8.4 and systemd 231-4.

Here's some output:

$ journalctl -b -1 -k

-- No entries --

$ journalctl -b -1

I send this mail for the second time since it seems to fail previously.
