Paul Haerle | I've been hacking around with network-related functionality from https://github.com/NixOS/nixpkgs/pull/169116 and needed to add the following files for outgoing https to work:
boot.initrd.environment.etc = {
"resolv.conf".text = "nameserver 1.1.1.1";
"ssl/certs/ca-certificates.crt".source = "${pkgs.cacert}/etc/ssl/certs/ca-bundle.crt";
};
boot.initrd.systemd.storePaths = [
# so nix can look up dns entries
"${pkgs.glibc}/lib/libnss_dns.so.2"
];
Size increase is imho neglectable, so is this something you'd want to add to the PR ElvishJerricco ? (using network.namservers instead of 1.1.1.1 ofc)

Paul Haerle | I think it's useful, because it enables me to run tools like nix and curl in my initrd :) | 22:32:46 |

@elvishjerricco:matrix.org | Interesting... | 22:32:59 |
@elvishjerricco:matrix.org | I dunno if we want that by default but I could see a configurable option for it | 22:33:24 |
Paul Haerle | In reply to @elvishjerricco:matrix.org I dunno if we want that by default but I could see a configurable option for it I think an option would work fine as well. Just see little harm besides a few kb. But i guess outgoing tls connections from your initrd are a fringe use case to begin with :D | 22:34:31 |

In stage 2, resolv.conf is managed by systemd-resolved. Should we just enable it in stage 1? | 06:52:28 |
@elvishjerricco:matrix.org | that's an interesting option. | 06:54:35 |
Paul Haerle | In reply to @oxalica:matrix.org In stage 2, resolv.conf is managed by systemd-resolved. Should we just enable it in stage 1? Sounds reasonable to me? At least if networking is enabled? | 09:01:49 |

Zhaofeng Li | What should we do to push https://github.com/NixOS/nixpkgs/pull/189676 forward? | 20:18:30 |
@elvishjerricco:matrix.org | Seems like it just needs the approval of one or two reviewers. I don't see any outstanding technical issues, aside from the slight initrd size increase that I'm personally ok with. Though I guess we could reasonably only include the tpm/fido libraries/packages when the user is actually using the feature | 20:25:50 |
flokli | I just pressed the button :-) let's get this in, if it ends up accidentally breaking something, we can always revert. | 22:56:55 |

colemickens | ElvishJerricco: have you looked at openvpn task for the network-initrd PR? I keep wishing it were merged... | 17:23:52 |
@elvishjerricco:matrix.org | colemickens: To me the bigger blocker is the question about whether/how to auto-configure interfaces, like how the scripted initrd networking does | 17:35:09 |
@elvishjerricco:matrix.org | That question needs to be answered. I wouldn't mind openvpn coming in a later PR | 17:35:22 |
@elvishjerricco:matrix.org | It's not clear to me that we should auto-configure interfaces, and if we should, it's not clear to me how, particularly because of people who just use networking.useDHCP rather than configuring individual interfaces | 17:36:41 |
@elvishjerricco:matrix.org | (though I guess that's deprecated isn't it? So we could just not support it with systemd stage 1 networking...) | 17:37:05 |
@elvishjerricco:matrix.org | Oh there's also boot.initrd.network.flushBeforeStage2, which is true by default with scripted initrd, but systemd-networkd behaves as though it's false right now | 17:38:18 |
@elvishjerricco:matrix.org |
When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition from the initramfs and to restart the service without breaking connectivity. This also means that when configuration is updated and systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up manually.
| 17:39:21 |
colemickens | Does it make sense to say init-networkd is only supported if you also use networkd in stage-2? | 17:40:57 |
colemickens | and at that point, can you just wholly use the stage-2's networkd config for stage-1, maybe letting the user override it if they wanted to? | 17:41:26 |
@elvishjerricco:matrix.org | Ehh.... Two problems. 1) We would only want to copy a subset of stage 2 config. For instance we probably can't expect to be able to bring up wireguard netdevs due to a lack of secrets. 2) I'm sure there are people who want to use e.g. NetworkManager in stage 2 but still want to e.g. unlock LUKS remotely in stage 1. | 17:43:02 |
@elvishjerricco:matrix.org | Aren't NetworkManager and systemd-networkd... a little bit mutually exclusive? | 17:43:21 |
@elvishjerricco:matrix.org | (I actually do not know) | 17:43:35 |
colemickens | eh, I think you're right enough either way | 17:44:03 |
colemickens | on both points | 17:44:11 |
colemickens | I'll think about it some more, I had forgotten about these things that do seem much more important than special support for openvpn | 17:44:36 |
@elvishjerricco:matrix.org | I think it'd be great to reuse some subset of stage 2 networkd configuration when possible, but I have no idea what subset we can automatically decide to use | 17:44:39 |
