 310                   Override the root partition on the final device. If left empty,
 311                   it will be mounted by PARTUUID which makes the kernel find the
 312                   appropriate disk automatically.

 317                   Do not symlink /var to /tmp, so that its content will persist
 318                   across reboots. When enabled, /var/run will still be linked
 319                   to /tmp/run.
