nix - 如何在家庭管理器中使用覆盖从不稳定安装 jbake

Question

添加不稳定 channel 后

nix-channel --add https://nixos.org/channels/nixpkgs-unstable unstable

我在 ~/.config/nixpkgs/overlays/package-upgrades/default.nix 下添加了一个覆盖

self: super:
let
  unstable = import <unstable> {};
in {
  jbake = unstable.jbake;
}

此叠加层已添加到 home.nix

nixpkgs.overlays = [ (import ./overlays/package-upgrades) ];

当我跑 home-manager switch有错误

0 + john@n1 nixpkgs $ home-manager switch
Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS

整个配置可以在 here找到.

如何使用 home-manager 和覆盖从不稳定升级单个属性？

此 thread on nixos discourse似乎相关。似乎在导入不稳定时也会应用叠加层，从而导致无限递归。尝试类似:

let
  unstable = import <unstable> {};
in {
  home.packages = with pkgs; [
    ...
  ] ++ (with unstable; [
    jbake
  ]);
}
