When I ran this on macOS: ``` nix build -f ci eval.singleSystem --argstr evalSystem aarch64-darwin --arg chunkSize 10000 --arg quickTest true -L --no-link ``` I get an error: ``` attrpaths-superset.json> error: creating directory '/nix/store/.links': Operation not permitted ``` It seems Nix commands executed to generate `attrpaths-superset.json` and run `nixpkgs-eval-*` try to unconditionally create `.links` directory in Nix store. This change points them to an empty Nix Store in a temporary directory.

There is a different approach to the same problem in #406307. |

There was a problem hiding this comment.
Judging by the number of rebuilds.. this change proposed here seems to throw off the comparison between master branch and the PR. No attrpaths match anymore, thus everything is supposedly rebuilt. Thus, I'd say this doesn't work as is.

@wolfgangwalther You're right, I didn't think this through. The resulting JSON points to the temporary directory: {
"AMB-plugins.x86_64-linux": {
"out": "/build/tmp.O0hRSdyCZL/8hz97h4k1d0pqb573v5z9lrym9dj6snj-AMB-plugins-0.8.1"
},
"ArchiSteamFarm.x86_64-linux": {
"out": "/build/tmp.O0hRSdyCZL/q8kf0nbw4n1pfiqily4mr9rwlk197yar-ArchiSteamFarm-6.1.6.7"
},
"CuboCore.coreaction.x86_64-linux": {
"out": "/build/tmp.O0hRSdyCZL/3gkhlgcgqyhpf1z3h8igqy1plq2sks2k-coreaction-5.0.0"
},And thus it cannot be matched between runs. I'll back off and let #406307 (hopefully) to proceed. |
