- Do not mount /var/volatile to be tmpfs always only when generating
readonly rootfs
- Generate var-volatile.mount unit when using system in readonly-rootfs
to mount /var/volatile as tmpfs
- for sysvinit, mount /var/volatile to be tmpfs if its not already
mounted so
- Use RequiresMountsFor instead of After=, so systemd figures out the
needed dependencies for making /var/volatile accessible for journald
and not us.
