| @abmantis:abcosta.com | Hey! Why is it that when I use nix develop (on some repo I've used already) it fetches and updates the packages automatically? It takes quite a while, and I would be happy most of the times to use the current packages I already used one day ago. any way to stop that? | 19:24:06 |
 @mewp:nurupo.pl | I don't use nix develop, so I'm not sure, but direnv with use flake definitely doesn't do that | 19:25:44 |
 tomberek | Do you have automatic GC turned on to run nightly? If so, a feature that might help you is "nix develop --profile ./tools". It makes a symlink to protect that stuff from GC. You can even enter that profile directly instead of the flake-defined one with "nix develop ./tools". | 20:11:57 |
| @abmantis:abcosta.com | ohhh, I do have GC running! | 20:23:23 |
| @abmantis:abcosta.com | I'll try that out! thanks a lot | 20:23:32 |

 Bryan | If you use nix-direnv (or flakeenv) and the flake itself hasn't changed, the environment should be cached and a gcroot added for it so that gc doesn't clean it up :) | 19:16:53 |
| @abmantis:abcosta.com | tomberek: using --profile did not make it :( | 21:16:12 |
| @abmantis:abcosta.com | the command I'm using is:
nix develop --profile ./nix-profile /home/acosta/dev/thirdparty/nix-environments#home-assistant | 21:16:37 |
| @abmantis:abcosta.com | In reply to @bryan.bennett:matrix.org
If you use nix-direnv (or flakeenv) and the flake itself hasn't changed, the environment should be cached and a gcroot added for it so that gc doesn't clean it up :) I think in this case using flakeenv would not work since the flake is in the nix-environments repo, not in the project repo | 21:17:12 |

| @mfed3:matrix.org | 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:matrix.org | Ran sudo nixos-rebuild switch --flake . | 01:49:02 |
| @mfed3:matrix.org | [mfed3@fed-gc:~/git/nixos-config]$ sudo nixos-rebuild switch --flake .
