 hexa | most boxes have just a wan interface and throwing static addresses and a gateway on it isn't hard | 02:27:07 |
| hexa | or do dhc | 02:27:13 |
| hexa | * or do dhcp | 02:27:14 |
 emily | I think useDHCP is a sufficient compatibility shim for probably the majority of NixOS boxes in existence | 02:27:32 |
| emily | but in the absence of scripted networking I don't think this file is too bad either, it is mostly just simple option mapping | 02:28:03 |
| emily | that openvswitch stuff is awful though :) | 02:28:10 |
| hexa | it feels like a code drop introducing technical debt for the most part | 02:29:07 |
| hexa | the awful part is that people will never migrate away from network.interfaces that way | 02:29:24 |
| hexa | * the awful part is that people will never migrate away from networking.interfaces that way | 02:29:44 |
| hexa | like, what would be so hard about just running networking.dhcpcd.enable with allowInterfaces = [ "eth0" ] instead of useDHCP? | 02:30:35 |
| hexa | and why the hell is it usedhcp? | 02:30:59 |
| hexa | * and why the hell is it useDHCP? | 02:31:19 |
| emily | I thought networkd didn't use dhcpcd | 02:31:29 |
| hexa | and not network.interfaces.<name>dhcp.enable | 02:31:33 |
| hexa | it does not | 02:31:38 |
| emily | I believe both exis? | 02:31:45 |
| emily | * I believe both exist? | 02:31:46 |
| hexa | I don't want to force people onto networkd | 02:31:47 |
| hexa | * I don't want to force people onto networkd specifically | 02:31:49 |
| hexa | I want to force them off of scripted networking | 02:31:57 |
| emily | well, I think the idea of useNetworkd was precisely to be able to move everyone from scripted networking to networkd without having to break every single networking configuration in existence | 02:32:17 |
| emily | I think it's a lot easier to sell a flag day when it doesn't break the most basic networking config | 02:32:32 |
| emily | gradually deprecating the old stuff is going to be easier after everyone is already running an implementation backed by the migration path | 02:32:53 |
| hexa | it boils down to us being bad at deprecating interfaces | 02:32:56 |
| hexa | do you think we should support the old option interface indefinately then? | 02:33:21 |
| hexa | * do you think we should support the old option interface indefinately then and just deprecated the backend? | 02:33:27 |
| emily | not necessarily | 02:34:00 |
| hexa | because I would really hope that the average nixos user would arrive at a place where they can apply 7 lines of config for an interface | 02:34:02 |
| hexa | * do you think we should support the old option interface indefinately then and just deprecate the backend? | 02:34:12 |
| hexa | https://wiki.nixos.org/wiki/Systemd-networkd#Examples already covers the basic use cases | 02:34:43 |
