2 years on and I keep bumping up against this issue on my laptop. Truth be told I've been bumping up against it for a long while, but an enforced break saw me have time to look into it.

I've tried shuffling dependencies in the scripts, but can't seem to sort it out.

Mine are transient nfs mounts, but if I forget to unmount one before rebooting it hangs and has to be power cycled.

$ cat /etc/devuan_version
chimaera

Love to hear any suggestions.
