Since #104722 (backported to 20.09 as 645b8a3), the boot process hangs for 3 minutes on this message:

[***   ] A start job is running for Wait for udev To Complete Device Initialization

Even a minimal configuration with just this:

  networking.wireless.networks.<ssid>.psk = <psk>;

as the only network-relevant config displays the same behavior.

I got the same delay + message while booting a recent nixos-minimal-20.09 iso.

In addition to the delay, with networking.useNetworkd = true;, the wireless interface is never configured at all it seems.

I haven't yet tried with nixos-unstable.

Reverting 645b8a3 fixes the issue.
