This reverts commit 872770286d.
This will fix fwknop as well (should have done it like this in the first
place, where was my mind...).
Conclusion: Did something stupid... :o - I am *so incredibly sorry*,
will be way more careful (was already careful, but apparently not
enought...) next time and use nox.
Sorry @everyone and thanks @calvertvl for noticing this.
