@elvishjerricco:matrix.org | still need the before. Requires dependencies don't cause runtime ordering | 01:39:07 |
Winter (she/her) | got it, wasn't 100% sure | 01:39:29 |
@elvishjerricco:matrix.org | and only lead to failure if the required unit fails before the requiring unit has even started | 01:39:31 |
Winter (she/her) | interesting | 01:39:49 |
@elvishjerricco:matrix.org | the other difference from Wants is that if the required unit isn't present at all, the requiring unit fails | 01:40:17 |
Winter (she/her) | okay, last thing: how do I control what hostname is sent to the DHCP server with networkd in initrd? when using scripted stage1, i get a static lease, but with networkd, the IP... increases for whatever reason? | 01:40:35 |
Winter (she/her) | i think it's the hostname? no idea tho | 01:40:41 |
@elvishjerricco:matrix.org | huh, can't say I've seen that behavior. But you can probably just set boot.initrd.systemd.contents."/etc/hostname".source = config.environment.etc.hostname.source; | 01:41:55 |
Winter (she/her) | thanks, i'll give it a shot | 01:42:10 |
Winter (she/her) | requiredBy = [ "sysroot.mount" ];
before = [ "sysroot.mount" ];
after = [ "dev-mapper-nixos.device" ];
bindsTo = [ "dev-mapper-nixos.device" ];
nothing redundant is here, right? just want to make sure before i reboot and have to rollback for the millionth time :/
| 01:42:51 |
@uep:matrix.org | presumably because your DHCP server is configured to use that hostname as the allocation, rather than the mac address | 01:43:06 |
@elvishjerricco:matrix.org | Winter (she/her): Also, I had to do boot.initrd.systemd.network.networks.<name>.dhcpV4Config.ClientIdentifier = "mac"; because my DHCP server on my router is a systemd-networkd one, and that was the only way I could figure out to get a statically assigned IP address to the mac address | 01:43:44 |
@elvishjerricco:matrix.org | otherwise it uses some other link identifier thingy | 01:44:10 |
@uep:matrix.org | I keep meaning to change mine to use a combination, because there are several laptops that sometimes use a certain docking station, and they all wind up with the same IP while there | 01:44:16 |
@elvishjerricco:matrix.org | but that should be stable and it should still serve the same ip address | 01:44:27 |
@elvishjerricco:matrix.org | In reply to @winterqt:nixos.dev
requiredBy = [ "sysroot.mount" ];
before = [ "sysroot.mount" ];
after = [ "dev-mapper-nixos.device" ];
bindsTo = [ "dev-mapper-nixos.device" ];

seems fine to me | 01:44:49 |
Winter (she/her) | In reply to @uep:matrix.org presumably because your DHCP server is configured to use that hostname as the allocation, rather than the mac address it's using the same hostname afaict | 01:44:59 |
Winter (she/her) | by this point i guess i'll just set systemd.network.enable = true ig | 01:45:29 |
@elvishjerricco:matrix.org | btw flushBeforeStage2 is off by default with systemd initrd networking | 01:45:41 |
@elvishjerricco:matrix.org | not sure if that affects things | 01:45:46 |
@uep:matrix.org | then i wonder what changes to make the server allocate a different lease rather than reuse the existing | 01:45:55 |
Winter (she/her) | no clue! | 01:46:33 |
Winter (she/her) | very weird | 01:46:35 |
Winter (she/her) | as after flushing, i always get the same lease | 01:46:43 |
Winter (she/her) | * as after flushing in stage2, i always get the same lease | 01:46:55 |
@uep:matrix.org | (since I assumed it was some unconfigured, dynamic hostname) | 01:46:46 |
@uep:matrix.org | perhaps some sniffing of requests is in order, assuming getting to the bottom of the issue is sufficiently interesting | 01:47:55 |
Winter (she/her) | In reply to @uep:matrix.org (since I assumed it was some unconfigured, dynamic hostname) fun news: it's also a completely random MAC address?? | 18:06:12 |
Winter (she/her) | i don't think that's default networkd behavior...? | 18:07:11 |
Winter (she/her) | nope: https://github.com/systemd/systemd/blob/e30b4c13570a5e4ec794d480d5371e9c739570d9/network/99-default.link#L17 | 18:07:46 |
