Dec 01 17:25:14 u1 systemd-remount-fs[75]: mount: /: can't find LABEL=cloudimg-rootfs.
Warning: journal has been rotated since unit was started, output may be incomplete.

On an older Ubuntu 18.04 container I have, the service contains ConditionVirtualization=!container. Should this be added back? I’m not finding where or why that was removed.

Probably so or alternatively edit your /etc/fstab to drop the cloudimg-rootfs entry.
