Issue

• This issue happens only if Persistent logging for the Journal is turned on in /etc/systemd/journald.conf or /var/log/journal exists on the root filesystem and /var or /var/log is on a dedicated filesystem

  # grep ^Storage /etc/systemd/journald.conf 
  Storage=persistent
  

  or

  # mount --bind / /mnt
  # test -d /mnt/var/log/journal; echo $?
  0
  # umount /mnt
  

• After a reboot, systemd-journald doesn't log to /var/log/messages

• After a reboot, journalctl --list-boots doesn't find any journal

  # journalctl --list-boots 
  No journal files were found.
  

• After a reboot, journalctl -b displays no log

  # journalctl -b
  No journal files were found.
