Sorry, I am no longer able to maintain here - at this moment I have no working NixOS/ZFS setup. |

Pinging @7c6f434c @Mic92 @gebner @matthewbauer, this is a trivial change without which the znapzend module doesn't work for new users, would like to have it merged. Should be applied to 18.03 as well. |

OK, I cannot test it but it makes a lot of sense. |
