Comment 5 for bug 1804603

Same issue here! No SSH-Daemon will start again! Happens after Shutdown, just a Reboot shouldn't affect the System.

received the package via unattended security updates (?)

2018-11-21 06:55:30 upgrade systemd:amd64 229-4ubuntu21.8 229-4ubuntu21.9

No relevance at all with btrfs, we use ext4
