 mfed3 | Hey everyone, been using nixos for about 2 years now, but finally doing some tests to migrate to flakes with my configuration of 2 hosts. Was following some basics on the nixos-wiki and right off the bat errors.
My steps were:
Enabled flakes and nix-command on the old style configuration
Refactored my configs a bit to have a modules and hosts folder at the top level
Ran nix flake init
Modified the file to look like this:
| 01:48:38 |
| mfed3 | Ran sudo nixos-rebuild switch --flake . | 01:49:02 |
| mfed3 | [mfed3@fed-gc:~/git/nixos-config]$ sudo nixos-rebuild switch --flake .

| mfed3 | The errors don't even point to anything in my files, I don't understand what it's trying to tell me | 01:51:18 |
| mfed3 | Maybe someone knows this common error means something specific that I forgot to do ? Can't even find the error searching for it | 01:53:06 |
 Charles | When using flakes and git, nix does not know files exist unless they are checked into git. Try running git add -AN and then trying again | 01:55:46 |
| Charles | * When using flakes and git, nix does not know files exist unless they are checked in or staged in git. Try running
`git add -AN` and then trying again | 01:56:42 |
| mfed3 | So my original config was a git repo but this one is not, I didn't realize it doesn't work at all without it being a git repo | 01:58:30 |
| mfed3 | Ok so can I just git init from that folder or do I need to delete the flake.nix and lock file and redo nix flake init? | 01:59:22 |
| Charles | If it's not a git repo then it should work | 02:00:04 |
| Charles | Make sure you didn't typo your paths in your nix code | 02:00:18 |
| Charles | Maybe try running git status to double check that it isn't a git repo | 02:01:09 |
| mfed3 | k I committed everything in there now, reran, same error | 02:03:08 |
| Charles | In reply to @charles:computer.surgery
Make sure you didn't typo your paths in your nix code Try this | 02:03:56 |
| Charles | The error looks like you wrote ./foo.nix but actually have ./bar.nix instead for example | 02:04:51 |
| Charles | That or it's not getting copied into the store, which would be the git thing | 02:05:15 |
| mfed3 | For modules, relative path to a folder from root of a flake would be ./hosts/file.nix not hosts/file.nix and no quotes around them in modules correct | 02:06:00 |
| mfed3 | Omg I'm a fuckin idiot, fatfingered a ../ in one of the imports 3 deep in one of the configs | 02:37:36 |
| mfed3 | Man the error messages are so useless lol | 02:37:57 |
| mfed3 | Thanks charles you were right after all :D | 02:39:01 |
| mfed3 | Works, system officially flakified | 02:44:24 |
 tomberek | That did not make a symlink? | 02:57:55 |

| @abmantis:abcosta.com | it does, but still I just ran nix develop --profile ./nix-profile /home/acosta/dev/thirdparty/nix-environments#home-assistant and it fetched stuff before opening the environment | 21:29:24 |

| mfed3 | Hey guys I have a question on autoupgrade, what does this actually do:
system.autoUpgrade = {
enable = true;
allowReboot = true;
flake = inputs.self.outPath;
flags = [ "--update-input" "nixpkgs" "--print-build-logs" ];
};
| 12:24:14 |
| mfed3 | Is that making the system run a nixos-rebuild switch automatically at 4:40 and build what is in the flake.lock | 12:25:09 |
| mfed3 | Or is that actually doing a nix flake update then building it | 12:25:43 |
