 @elvishjerricco:matrix.org | which is way smaller than the dumbest scripted initrd we can generate | 22:02:50 |
 @lily:lily.flowers | Should we add another pkgs.systemdStage1Cryptsetup or do something from the module's side? | 22:04:02 |
 @aktaboot:tchncs.de | where does the withCruptsetup come from ? | 22:04:13 |
| @elvishjerricco:matrix.org | I think at this point we need a feature matrix system | 22:04:15 |
| @lily:lily.flowers | (since obviously adding more combinations, like systemdStage1NetworkCryptsetup would be kinda dumb) | 22:04:19 |

I think at this point we need a feature matrix system Yeah that was my thought | 22:04:25 |
| @elvishjerricco:matrix.org | aktaboot: it's from where systemdStage1 is defined in all-packages.nix | 22:04:42 |
| @elvishjerricco:matrix.org | Lily Foster: Yea I think we should turn the with* things into nix options and then cache the most common configurations | 22:05:00 |
| @elvishjerricco:matrix.org | * Lily Foster: Yea I think we should turn some of the with* things into nix options and then cache the most common configurations | 22:05:18 |
| @lily:lily.flowers | Yeah, I'll agree to that | 22:05:59 |
| @elvishjerricco:matrix.org | or... hm... Actually, just using pkgs.systemd is barely bigger than the current systemdStage1. So maybe we have a minimal and we have a full | 22:06:11 |
| @elvishjerricco:matrix.org | and leave it at that | 22:06:14 |
| @lily:lily.flowers | How barely? I'd be okay with just replacing systemdStage1 and systemdStage1Network with just systemd if the size difference is minimal (like within a megabyte or so) | 22:07:22 |
| @elvishjerricco:matrix.org | It is within a megabyte | 22:07:34 |
| @lily:lily.flowers | Yeah, no reason to keep the separation then I guess | 22:07:53 |
| @elvishjerricco:matrix.org | oof but enabling cryptsetup stuff just to enable networking stuff is a bummer, adding a bunch of extra unneeded space | 22:09:14 |
| @elvishjerricco:matrix.org | but that should get fixed by the smarter condition I guess | 22:09:26 |
| @elvishjerricco:matrix.org | let me try that | 22:09:27 |
| @aktaboot:tchncs.de | is it me, or we could use withFido2 and withTpm2tss in the initrd.nix ? | 22:09:29 |
| @aktaboot:tchncs.de | but that would basically be withCryptsetup, I guess | 22:11:16 |
| @elvishjerricco:matrix.org | I need to just make a complete matrix of these sizes to analyze it.... | 22:13:24 |
| @elvishjerricco:matrix.org | Redacted or Malformed Event | 22:55:27 |
| @elvishjerricco:matrix.org | I'll convert that to a gist... | 22:56:34 |
| @elvishjerricco:matrix.org | Ok here are the results, along with a necessary nixpkgs patch file: https://gist.github.com/ElvishJerricco/ca36d26fd30b78b211aea10604b9885e | 22:57:59 |
| @elvishjerricco:matrix.org | (note that tpm2, fido2, and luks flags are all redundant unless accompanied by cryptsetup flag) | 23:09:05 |
| @elvishjerricco:matrix.org | Actually, I edited it with some fancy code to remove the redundant ones and include the non-systemd ones | 23:34:57 |

 @mlyx:matrix.org | https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/tasks/lvm.nix
Can we disable lvm by default? For those who don't use lvm, it adds lots of unnecessary stuff in initrd. | 00:22:43 |
| @elvishjerricco:matrix.org | mlyx: We have actually have a PR for that: https://github.com/NixOS/nixpkgs/pull/183314 | 00:25:19 |
| @elvishjerricco:matrix.org | (it says swraid but it also does lvm, and we probably want to do bcache in there too) | 00:25:35 |
| @elvishjerricco:matrix.org | actualy, hm, it looks like that PR doesn't actually disable LVM depending on stateVersion like it does for swraid... so there's a reason it's not merged :P | 00:26:54 |
