[systemd-devel] journal on btrfs subvolume, failed unmounting /var/log/journal

[Chris Murphy]

It looks like var-log-journal.mount is called before systemd-journald is finished using it. Is the failure message merely cosmetic? The file system comes up clean on reboot so I'm pretty sure it's being cleanly unmounted despite this message.
