TODO

The NixOS VM test currently fails for me, but does so equally before this commit, on nixos-unstable:

allowFromLighthouse: must succeed: ping -c5 10.0.100.3
allowFromLighthouse # ping: connect: Network is unreachable
allowFromLighthouse: output: 
cleanup
kill machine (pid 60)

Maybe there is a race?

Looked at the NixOS tests, they should be fixed by #273273.

[numinit]

Should we support this too (in another PR)?

slackhq/nebula#929

Bet this would have fixed the test flakiness too.

@nh2 Test flakiness fix is merged. Once we merge this we'll do another PR for the systemd ready socket.
