• Editing /etc/fstab safely: UUIDs, nofail, x-systemd options and findmnt --verify

  A bad /etc/fstab line can drop a system to an emergency shell on the next boot. This methodology uses UUID= instead of device names, nofail and x-systemd.device-timeout= for optional mounts, and findmnt --verify plus mount -a to test the file before rebooting.
