Why does mdraid needs configuration with systemd enabled? iirc the decision was made not to just pull in all that (meaning kernel modules + tooling), because not that many people use it.
in the old initrd, it's just enabled by default. | 14:33:46 |
 @elvishjerricco:matrix.org | but that's just a guess | 14:33:53 |
| @andreas.schraegle:helsinki-systems.de | so there's an option, that you can enable for it. would need to check what it's called | 14:33:59 |
 Mic92 | Andreas Schrägle: but even enabling swraid seems to fix. one has to write configuration | 14:34:14 |

| Mic92 | This test has to add configuration to work | 14:35:19 |
| @andreas.schraegle:helsinki-systems.de | ah. interesting. the old initrd probably just does mdadm --scan or something like that? | 14:35:37 |
| @elvishjerricco:matrix.org | Mic92: I would look at the foobarCommands options and try to see what might be setting those | 14:36:42 |
| @elvishjerricco:matrix.org | if that's not the problem then something is much more confusing than I would expect :P | 14:37:00 |
| @andreas.schraegle:helsinki-systems.de | ah, looking at nixos/modules/tasks/swraid.nix, it seems like there's some udev rule stuff happening | 14:37:34 |
| Mic92 | Yeah. I think the udev rules are missing | 14:37:49 |
| @elvishjerricco:matrix.org | interesting... | 14:37:59 |
| Mic92 | Janne Heß: you merged this into the swraid module, do you know why udev is disabled? | 14:38:40 |
| @elvishjerricco:matrix.org | oh wow yea it just wholesale cps those udev rules lol | 14:38:44 |
| @elvishjerricco:matrix.org | Mic92: I think we just decided not to include any foobarCommands on principle. | 14:41:33 |
| Mic92 | ElvishJerricco: ok, but including udev rules is fine, no? | 14:41:52 |
| @elvishjerricco:matrix.org | eh, the way that particular thing works is iffy | 14:42:31 |
| Mic92 | what is the current way? | 14:42:45 |
| @elvishjerricco:matrix.org | we don't have a phase where random commands can be run | 14:42:47 |
| @elvishjerricco:matrix.org | the scripted initrd does | 14:42:59 |
| @elvishjerricco:matrix.org | (i.e. the extra-utils derivation) | 14:43:07 |
| Mic92 | Can I now just include a package that gets merged somehow? | 14:43:09 |
| @andreas.schraegle:helsinki-systems.de | shouldn't boot.initrd.services.udev.packages = lib.mkIf cfg.enable [ pkgs.mdadm ]; do that? | 14:43:16 |

shouldn't boot.initrd.services.udev.packages = lib.mkIf cfg.enable [ pkgs.mdadm ]; do that? Oh, yes | 14:43:26 |
| Mic92 | will test | 14:44:00 |
| @andreas.schraegle:helsinki-systems.de | nixos/modules/tasks/swraid.nix already does that, so it should already work without a config. idk why the test adds one. | 14:50:29 |
| @elvishjerricco:matrix.org |
the test
What test?
