There are two cases to think about here:
1) rumpdisk was booted as a bootstrapped task
2) rumpdisk was called from a userspace translator
In both cases, you need @/dev/rumpdisk:/dev/X to be recognised as a valid
access rule.
Perhaps I confused myself and maybe it is not needed, you could be correct.
I will test again without it.
