 David Arnold (blaggacao) | bud runs commands reproducibly in a complete isolated environment. So the only thing that can cause that, is as you correctly deducted, a variation of the binary itself in the nixpkgs version that bud uses. | 12:07:00 |
| David Arnold (blaggacao) | bud.inputs.follows.nixpkgs = "nixos" (as in recent DevOS) instructs to use the same nixpkgs as uses DevOS as nixos input. | 12:08:58 |
| David Arnold (blaggacao) | That, in turn is pinned to releas-21.05 by default. | 12:09:42 |
| David Arnold (blaggacao) | If within this setup, it's not working, then it's a bug. 🤕 | 12:10:01 |
| David Arnold (blaggacao) | If you're trying to use a different nixos version, it might work if you remove that line with follows since bud itself is pinned to nixos-21.05 if not overridden. | 12:12:06 |
| David Arnold (blaggacao) | But that assumes that this nixos-21.05' nicos-rebuild is actually compatible with that other nixos version. I wouldn't give an unconditional guarantee, but probably it is. | 12:13:22 |

But that assumes that this nixos-21.05' nicos-rebuild is actually compatible with that other nixos version. I wouldn't give an unconditional guarantee, but probably it is. This would work because this way I'm going to use the nixos-21.05 commit inside the bud's flake.lock, right? | 12:14:26 |
| David Arnold (blaggacao) | Btw., this is one of the reasons why we've been discussing replacing those nixos tools with deploy-rs -- a generic, "flakes-native" profile (incl. system) deployer. | 12:14:27 |

This would work because this way I'm going to use the nixos-21.05 commit inside the bud's flake.lock, right? Almost: inside devos' flake.lock for the bud input. flake.lock always contains the entire dependency tree. | 12:15:30 |
| David Arnold (blaggacao) | In this case, that would be duplicate versions of nixpkgs. | 12:15:52 |
| David Arnold (blaggacao) | Usually, you'd be seeing something like nixpkgs_2, etc. | 12:16:31 |
| David Arnold (blaggacao) | Ah, sry. Your reply wasn't wrong. I just read it wrong 🙂😎 | 12:17:20 |

| @zrsk:matrix.org | I wasn't clear, mea culpa. | 12:18:01 |

Btw., this is one of the reasons why we've been discussing replacing those nixos tools with deploy-rs -- a generic, "flakes-native" profile (incl. system) deployer. This is too advanced for me now, I just started using DevOS, however I'll remember | 12:18:31 |
| @zrsk:matrix.org | However commenting the line you told me didn't work, I exited the dev shell and I run nix flake update, then I re-entered in the dev shell to run bud rebuild test but same problem. | 12:19:50 |
| @zrsk:matrix.org | When I re-entered with nix develop it re-built something (nixitself for sure, the command I mean) | 12:20:41 |
| @zrsk:matrix.org | What am I missing? | 12:20:50 |
| David Arnold (blaggacao) | It's simple. What it does:
- builds a profile locally
- pushes the closures over ssh
- runs the profile's switch mechanism over ssh (in the case of a typical nixpks system profile, that would be on of those nixos-* commands)
| 12:20:59 |

| David Arnold (blaggacao) | What's you nix version? | 12:24:31 |
| David Arnold (blaggacao) | Line 45 in devos might still get you hooked on the wrong nixpkgs version, even for bud. That's a bug in nix up to 2 weeks ago. | 12:25:45 |
| David Arnold (blaggacao) | * What's your `nix` version? | 12:26:04 |
| David Arnold (blaggacao) | * Line 45 in devos might still get you hooked on the wrong `nixpkgs` version, even for `bud`. That's a bug in `nix` present until to ~2 weeks ago. | 12:27:35 |

What's your nix version? Do you mean inside for the Flake(.lock)? | 12:28:39 |
| @zrsk:matrix.org | Or do you mean that the bug is in the host's Nix (that I use to run nix develop) | 12:28:56 |
| @zrsk:matrix.org | My host's Nix version is the latest in the unstable-channel | 12:29:38 |
