 @elvishjerricco:matrix.org | I actually was unable to find one that hasn't done the necessary mkIf in nixpkgs | 13:32:48 |

I actually was unable to find one that hasn't done the necessary mkIf in nixpkgs It might only be the zfs one that was missed then. I haven't done a pass myself to look for others | 13:33:49 |
| @elvishjerricco:matrix.org | Hm I thought I tested that one... | 13:34:30 |
| @elvishjerricco:matrix.org | ok the assertion just isn't working for some reason | 13:41:02 |
| @elvishjerricco:matrix.org | Or... the way I'm testing it isn't working? I'm confused | 13:42:08 |
| @elvishjerricco:matrix.org | Yea wtf assertions?
$ nix eval -f ./nixos --arg configuration '{fileSystems."/" = { device = "fo"; fsType = "zfs"; }; boot.loader.grub.device = "nodev"; networking.hostId = "deadbeef"; }' config.boot.initrd.postDeviceCommands
<very much not the empty string>
$ nix build -f ./nixos --arg configuration '{fileSystems."/" = { device = "fo"; fsType = "zfs"; }; boot.loader.grub.device = "nodev"; networking.hostId = "deadbeef"; }' system
<builds fine>

 @aktaboot:tchncs.de | but doesn't stage2 happen after mounting the rootfs ? (which in some cases is luks encrypted) so how would that be ? | 13:45:02 |
| @aktaboot:tchncs.de | only reading it from the comments in stage-1.nix | 13:45:24 |
| @elvishjerricco:matrix.org | aktaboot: The file systems that have to be mounted in stage 1 also need to have their LUKS drives decrypted in stage 1 | 13:45:32 |
| @elvishjerricco:matrix.org | But this is not all file systems | 13:45:48 |
| @elvishjerricco:matrix.org | It's not uncommon to have file systems and disks that only need to be done in stage 2 | 13:46:17 |
| @elvishjerricco:matrix.org | but we currently always do luks in stage 1 | 13:46:25 |
| @elvishjerricco:matrix.org | You can do it in stage 2 yourself by configuring /etc/crypttab though | 13:46:36 |

| @aktaboot:tchncs.de | okay I see 👍. Also is this stage1/2 thing nixos specific ? I couldn | 13:46:49 |
| @aktaboot:tchncs.de | * okay I see 👍. Also is this stage1/2 thing nixos specific ? I couldn't find info from other distros | 13:47:07 |
| @elvishjerricco:matrix.org | Lily Foster: Yea I see. I just can't figure out why the assertion didn't trigger for me | 13:47:21 |
| @elvishjerricco:matrix.org | Like, I can see the option's value is not the empty string with nix eval | 13:47:37 |

okay I see 👍. Also is this stage1/2 thing nixos specific ? I couldn't find info from other distros no, other distributions just don't call it stage 1 (the initramfs stage) and stage 2 (the actual system stage). | 13:50:14 |
| @elvishjerricco:matrix.org | Yea the systemd docs try to exclusively use the terms "initrd" and "host" for what we prefer to call "stage 1" and "stage 2" respectively | 13:50:58 |
| @elvishjerricco:matrix.org | initramfs is another commonly used name though since it's technically more accurate (no one uses literal ramdisks anymore, which is what rd stood for) | 13:51:24 |
| @aktaboot:tchncs.de | oh okay so stage2 ends with pivot-root iiuc ? | 13:52:11 |
| @elvishjerricco:matrix.org | stage 1 ends with systemctl switch-root (or switch_root in the traditional initrd) | 13:52:40 |
| oddlama | no stage 1 pivots to stage 2 | 13:52:42 |
| @elvishjerricco:matrix.org | stage 2 just shuts down when it ends | 13:52:54 |

Lily Foster: Yea I see. I just can't figure out why the assertion didn't trigger for me Oh, yeah, no clue there | 13:53:00 |
| @elvishjerricco:matrix.org | i.e. when you power off / reboot | 13:53:02 |
| @aktaboot:tchncs.de | okay so stage2 is just the normal os stuff :) | 13:53:09 |
| @aktaboot:tchncs.de | thanks for the clarificatiosn 👍 | 13:53:35 |
| @lily:lily.flowers | In reply to @elvishjerricco:matrix.org
stage 2 just shuts down when it ends We could designate the final shutdown ramfs pivot stage-3 (/s) | 13:53:39 |
