 Erik | Hey folks, I authored https://github.com/nix-darwin/nix-darwin/pull/1530. Looks like you are right; I did a fresh install of MacOS and got this error on bootstrap… and then blindly assumed therefore the issue would persist after that as well. I used nh darwin after that which does give me the error every time, but sudo darwin-rebuild doesn't.Shall I change the PR to only update the bootstrap command to use sudo -i? I can investigate what nh is doing separately. | 17:30:37 |

| Erik changed their display name from Erik to edejong. | 17:33:47 | |
| Erik | Oh and thanks for all the amazing work on nix-darwin. I love it. | 17:34:39 |
 samasaur | yeah that sounds like a nh bug | 17:37:44 |
| samasaur | or at least they are not working around that message the way that we are | 17:37:54 |
| samasaur | what's the exact command you're running for the bootstrap? | 17:38:49 |
 skyraider | Yeah, it is solved by a PR but not merged to 25.05 | 17:43:41 |
| skyraider | I have again done an init with unstable | 17:43:56 |
| skyraider | How do we switch from unstable to stable and vice-versa | 17:44:55 |
| skyraider | is there a command or where do all do I have to manually change in flake.conf | 17:45:20 |
| samasaur | just change your inputs in flake.nix | 17:46:36 |
| samasaur | and then rebuild | 17:46:43 |
| samasaur | and then maybe rebuild again to make sure you're using the version of darwin-rebuild from your new channel | 17:47:07 |
| Erik | sudo nix run nix-darwin/master#darwin-rebuild -- switch as in the docs, I made sure to follow the flake instructions verbatim | 18:18:48 |
| Erik | Perhaps that’s the nix run already causing the warning before darwin-rebuild even does anything? Either way that one’s easily solved with sudo -i, it’s a one-off anyway | 18:20:54 |
| samasaur | yeah I think you're right | 19:02:41 |
| Erik | I’ll go over the documented commands tomorrow to verify, and will update the PR | 19:58:53 |

| samasaur | I don't understand what's wrong with C++ interop... | 04:03:58 |
| samasaur | it's fine with import CxxStdlib but it seems like all the bridging functionality is missing | 04:05:20 |
| Erik | sudo nix run nix-darwin/master#darwin-rebuild -- switch throws the warning before even fetching nix-darwin, so that’s just what you get when running sudo nix <anything> | 08:04:39 |
| Erik | I tested all commands in README.md: sudo nix run nix-darwin/master#darwin-rebuild -- switch throws the warning before even fetching nix-darwin, so that’s just what you get when running sudo nix <anything>. Same for sudo nix-channel.I updated the PR to no longer suggest using sudo -i when running darwin-build or darwin-uninstall because those indeed do not emit the warning :) | 08:31:21 |
| Erik | Somewhat related: I was apprehensive to use nix-darwin when I first tried it because of this warning, but also because nix config check throws a fit about having two versions of nix installed. I realise now how little this matters, but coming from using brew doctor this really seemed like an issue: in my mind a clean install of nix-darwin made my nix installation “unhealthy".Do you think it’d be worthwhile adding a few lines about this to README.md for newcomers, to explain the various options you have?

If so, I’d be happy to add that | 08:44:56 |

If so, I’d be happy to add that. And just out of curiosity, what’s the reason for nix-darwin’s version of nix lagging so far behind? | 08:48:22 |
| Erik changed their display name from edejong to Erik. | 09:21:58 | |
 ivy | use nh it only ask for sudo when needed | 09:29:23 |
| ivy | which is when the actual switch happens | 09:29:35 |
| Erik | nh doesn’t seem to change the home dir though, so essentially running sudo instead of sudo -i. Meaning I get that warning every time I run it. It’s not harmful but it’s not pretty either. | 09:31:03 |
 toonn | I think it does mess things up if you manage channels. | 09:32:19 |
