 hexa (clat on linux when) | meh | 14:45:42 |
| hexa (clat on linux when) | yeah, nvm | 14:45:51 |
| hexa (clat on linux when) | bootstrapping the package set doesn't work with minimal | 14:45:59 |

| Sandro 🐧 | hehe, let me try that | 14:47:59 |
 emily | you could build with python3 and deploy with minimal but I'm also guessing that's hard for a billion reasons | 14:50:04 |
| Sandro 🐧 | that shouldn't be that hard to do but then you have no test coverage if something is missing | 14:58:06 |
| emily | yeah | 15:03:48 |
| emily | well hopefully IfState is going to have end-to-end NixOS tests… right? :) | 15:03:57 |
| emily | not like you can unit test most of the really important stuff there | 15:04:05 |
 @marcel:envs.net | In reply to @emilazy:matrix.org
well hopefully IfState is going to have end-to-end NixOS tests… right? :) The funny thing is that he did not really had an idea how to implement automatic tests and them I showed him Nixos tests and now there is nix code upstream. But I've already have VM tests in my nixpkgs fork on the ifstate branch | 15:05:00 |

| Sandro 🐧 | This got me pretty far. pyroute2 is failing for some seemingly unrelated error. | 16:25:48 |
 ElvishJerricco | I'm not 100% opposed to this but I certainly don't like it | 17:36:52 |
| ElvishJerricco | I mean I can think of how to do it with no new features too | 17:37:08 |
| emily | would you like it if we just… made the closures of things small enough that we can use it for everything? | 17:37:15 |
| emily | without the current hacks | 17:37:23 |
| ElvishJerricco | i.e. make a derivation that creates symlinks to everything listed in a ${closureInfo}/store-paths | 17:37:38 |
| ElvishJerricco | that's really not going to happen | 17:37:47 |
| emily | I genuinely think it could! | 17:38:04 |
| emily | what do you think the blockers would be? (we could discuss in the systemd room) | 17:38:12 |
| ElvishJerricco | even if we split binaries from everything else in every relevant derivation (which is a lot of derivations), there's still way more binaries than necessary in a lot of those derivations | 17:38:33 |
| emily | it doesn't have to be a monolithic bin, we do split out individual binaries into their own outputs when necessary | 17:39:02 |
