New comment by bitmeise on void-packages repository https://github.com/void-linux/void-packages/pull/27534#issuecomment-754596098 Comment: Because git blame says you have been fiddling with almost all lines of the file, I thought you might know what's happening here in more detail. Anyway, in IRC I was told that it is fine if the package *builds* without specifying a manual stack.yaml -- which it does on all archs according to the checks. I should also pin an LTS version. According to the manual https://github.com/void-linux/void-packages/blob/master/Manual.md#pkgs_haskell this can happen via a stack.yaml which already comes with the upstream sources. As all of the above is the case, **I consider this task done**.
