 @elvishjerricco:matrix.org | we could just tell users "hey fuck off and stop using a very dumb configuration" but something tells me that comes off a bit too rude :P Plus who knows if someone has a legit reason for that config. | 00:04:27 |
 Arian | what constitutes a "small ESP" | 08:54:01 |
| Arian | It would be nice that if we detect an existing small ESP we suggest setting up an XBOOTLDR partition automatically | 08:54:24 |

It would be nice that if we detect an existing small ESP we suggest setting up an XBOOTLDR partition automatically What would be a good way to implement something like this? I guess the install-systemd-boot.py script could print a warning if the ESP is smaller than size X and link to the XBOOTLDR man page. | 17:47:33 |
| @nikstur:matrix.org | Well and it would need actual support in NixOS for XBOOTLDR: https://github.com/NixOS/nixpkgs/pull/226692 | 17:50:53 |
 colemickens | I don't remember if I mentioned it there but you can cheat with bind mounts, which is what I do with lanzaboote. | 18:04:14 |

| @passion-fruit:matrix.org | Hello! Is it possible to have usb devices appear in /dev during stage 1, if you for example use one as an encryption key? It might just be as simple as loading a kernel module but I'm really stuck here :-) | 14:26:23 |
| @elvishjerricco:matrix.org | Fruity Passions: yea you probably just need a module added to boot.initrd.availableKernelModules | 14:29:45 |

Hello! Is it possible to have usb devices appear in /dev during stage 1, if you for example use one as an encryption key? It might just be as simple as loading a kernel module but I'm really stuck here :-) my guess is on usb_storage | 14:45:44 |
 @linus:schreibt.jetzt | what kind of USB device? | 14:46:27 |
| @linus:schreibt.jetzt | you'll need a USB controller driver, though it's likely that that's already covered by what nixos-generate-config produces (typically xhci_pci) | 14:51:32 |
| @linus:schreibt.jetzt | and depending on what kind of USB device you may also need a driver (like usb_storage if it's an older or less fancy USB storage device, or uas for newer ones) | 14:52:11 |
| @elvishjerricco:matrix.org | If you want a brute force solution, you could probably just import the all-hardware.nix module out of nixpkgs | 14:52:30 |
| @linus:schreibt.jetzt | but if it's a yubikey or something there's no kernel-side driver for it | 14:52:50 |
| @passion-fruit:matrix.org | In reply to @linus:schreibt.jetzt
what kind of USB device? Plain ol USB 2.0. It's model comes up as "FlashDisk" and it's very old (I think it's only a gig in size). | 15:26:03 |
| @passion-fruit:matrix.org | In reply to @oddlama:matrix.org
my guess is on usb_storage Already loaded by hardware-configuration but thanks for the guess :) | 15:27:10 |

If you want a brute force solution, you could probably just import the all-hardware.nix module out of nixpkgs I could try that? is it possible to, if it works, narrow it down afterwards? | 15:28:11 |

| @elvishjerricco:matrix.org | Yea I guess you could copy the code out of the module and then bisect it by commenting out one half at a time | 15:29:57 |
| oddlama | In reply to @passion-fruit:matrix.org
I could try that? is it possible to, if it works, narrow it down afterwards? Does the stick show up in stage2? If so, just check lsmod for relevant modules. | 15:37:52 |
| oddlama | If the device doesn't show up at all, you might be missing xhci_hcd xhci_pci or something like that | 15:38:51 |
| @passion-fruit:matrix.org | In reply to @oddlama:matrix.org
If the device doesn't show up at all, you might be missing xhci_hcd xhci_pci or something like that hmm i'm missing xhci_hcd but not the pci variant. could that perhaps be it? | 15:49:18 |
| oddlama | Depends on which controller is in use for the usb port | 15:52:33 |
| oddlama | sometimes xhci_hcd is pulled in as a dependencies, so not sure if that one is the missing link | 15:53:26 |
| oddlama | Try lsusb -t in stage 2 to see which driver is in use | 15:54:13 |
| @passion-fruit:matrix.org | that did it! Thank you so much :) - i checked lsusb -t after booting with the live iso and the usb controllers were using hcd. added xhci_hcd and now it works without issue | 16:24:57 |

 @lily:lily.flowers | So why is boot.initrd.services.lvm.enable a hidden option if it is required to enable it for systemd-stage-1 whenever you have a LVM needed for root | 20:10:35 |
| @lily:lily.flowers | (I, uh, spent longer than I wish I had the last few weeks banging my head against that) | 20:10:52 |
| @lily:lily.flowers | (until I found that option) | 20:11:05 |
