override.conf already existed on esh-docker-vm (dockerd ExecStart), so
the creates: guard skipped the step and the After=remote-fs.target
directive was never written. Use a distinct filename
(10-after-remote-fs.conf) that systemd merges alongside override.conf,
and guard on content rather than file existence so a stale file can't
silently skip.
Adds _netdev,nofail to the 4 10.0.50.50 NFS lines in /etc/fstab and a
docker.service drop-in (After=remote-fs.target) so Docker waits for the
NFS mounts before starting NFS-bind containers. Root cause of paperless
Exited(255) on every reboot. Idempotent; backs up fstab; no reboot.
