 dantefromhell | CRTified: The downside is this woukd only work with raspberrys plus I dont use the SD-Cards (long term reliability) since USB boot is now possible. | 10:41:56 |
| dantefromhell | From research it feels possible to get NixOS LIVE booted on all devices (kexec, pxe, usb sticks) so my hope is to build something nix-based from there for installation & management. | 10:46:14 |

You are free to create arbitrary layouts, so you can dd it on other media, too. I'm using RockPis and boot them from NVMe :) But I get your point, the same thing for x86 might be a bit more effort I think | 10:47:07 |
| dantefromhell | The first issue I recognized with colmena is the hostname match check for local deploys.
That breaks fresh installs and machine renames, no? | 10:47:21 |
| dantefromhell | CRTified: the dd approach is also suboptimal with differing disc size. it needs some post-processing... | 10:48:47 |
| CRTified | The aarch64 installer image autoresizes on boot | 10:49:21 |
| dantefromhell | CRTified: and stuff like ZFS raidZ might be impossible (would need to test) | 10:50:17 |
| CRTified | https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/installer/sd-card/sd-image.nix#L242-L267 here's what's done to expand on boot | 10:51:01 |

That breaks fresh installs and machine renames, no? When renaming machines, you can override which node apply-local selects with --node. For fresh installs, you need to run the activation script when chrooted into the new root (ex: the external script I linked) and the normal logic doesn't work. | 18:21:34 |

| dantefromhell | * yeah I feel there's this recursive dependency on nix all over the nix ecosystem | 11:20:53 |

Will check them out ASAP | 11:21:57 |

| snartvellental | hey folks, using colmena with joy, i am using it in CI and was wondering how people cache colmena builds on CI servers? | 08:03:02 |
 Linux Hackerman | snartvellental: you can use a Nix binary cache. Unfortunately there's no stable interface for populating a binary cache currently, but you can put `extra-substituters = file:///path/to/persistent/cache/dir/?trusted=1` in a nix.conf that gets picked up for the build, and use `nix copy --option experimental-features nix-command --all --to file:///path/to/persistent/cache/dir/` at the end of the build | 08:07:35 |
| Linux Hackerman | You can also use some S3-compatible storage rather than local storage if you prefer | 08:08:10 |
| snartvellental | I have played around with cachix in the past, thanks for your message Linux Hackerman , I will have a look :) | 08:08:58 |
| Linux Hackerman | Oh yeah you can use cachix too, but I was assuming that local storage without bandwidth restrictions might be preferable | 08:09:32 |
| Linux Hackerman | Also, sooner or later you're probably going to want to clean the storage up. There's currently no good mechanism for this, the easiest way is to just delete everything, but of course that means everything's gone... | 08:11:35 |
| snartvellental | yeah, then most likely one would resort to S3 with proper lifecycle rules in place | 08:14:19 |
| snartvellental | nix copy sounds like a new command, haven't seen that one | 08:16:20 |
| Linux Hackerman | there used to be nix-push, but that was removed in favour of the unstable nix copy interface 🙃 | 08:36:14 |
| snartvellental | why is nix such a big ocean lol :D sometimes I feel like i've seen 5% or 0,05% | 11:23:03 |
 Buckley | Because nix invites the user to jump into the whole stack and mess around :o | 13:05:35 |
| CRTified | Interesting. I'm currently not at home and tried apply-local for the first time to update my laptop. It fails and claims my machine isn't a NixOS machine 🤔 | 13:48:31 |
| Zhaofeng Li | Which versions of nixpkgs and Colmena? It doesn't look like they changed the format of /etc/os-release again | 18:59:04 |

 Jane Jasperous | hi, im configuring my systems using colmente to deploy in my network. I'd like to have some machines running 21.11 others 22.05 other unstable. I get working this for packages, but not for full nixos system (modules,...) | 12:27:06 |
