| @khalilsantana:matrix.org | Hi, is there a proper way to get colmena to nixos-rebuild --upgrade multiple hosts? I can use the exec sub-command but AFAIK that will build in every node, which seems wasteful | 03:06:51 |
 Wanja Hentze | wait, are you using channels on the hosts? | 08:30:26 |
| @khalilsantana:matrix.org | Doesn't all nixos installs use channels? (I'm a newbie, so I just looked up at the manual on how to upgrade nixos and that was one of the ways listed) | 13:10:05 |
| Wanja Hentze | No, I've never seen them used with colmena | 13:16:06 |
| Wanja Hentze | colmena evaluates the entire configuration not on the hosts but on the deploying machine | 13:16:40 |
| Wanja Hentze | you would usually pin your nixpkgs revision etc. either via flakes or some other mechanism | 13:17:03 |
