 crushing-smite | * There's also this warning each time I rebuild:
"""
evaluation warning: The combination of systemd.network.enable = true, networking.useDHCP = true and networking.useNetworkd = false can cause both networkd and dhcpcd to manage the same interfaces. This can lead to loss of networking. It is recommended you choose only one of networkd (by also enabling networking.useNetworkd) or scripting (by disabling systemd.network.enable)

| crushing-smite | Same | 22:21:53 |
| K900 | Try removing the forced regulatory domain on cfg80211 and adding it to the hostapd config instead? | 22:24:08 |
| crushing-smite | how to? | 22:25:01 |
| K900 | Honestly for starters just remove the boot.extraModprobeConfig | 22:27:57 |

 Nigel | May I ask how to work around networking.useNetworkd = true; causing activation to fail (stalled indefinitely) after services are stopped and the vps inaccessible via ssh. | 21:20:18 |
| K900 | It is not perfect | 21:23:59 |
| K900 | You probably want to see what it actually sets up | 21:24:04 |
| Nigel | I added -v to the switch command but it didn't help. It was copied from a near identical vps that I intended to transfer a mailserver from (and worked). | 21:25:58 |
| K900 | Not like that | 21:26:21 |
| K900 | Inspect the generated networkd units | 21:26:57 |
| Nigel | I guess using nix before activation - please may I ask how to look at this? | 21:29:42 |
