After changing any Nix-managed config in

~/.config/dotfiles

, the system must be rebuilt for changes to take effect. Nix store symlinks are read-only — you cannot edit them in place.

在修改

~/.config/dotfiles

中任何由Nix管理的配置后，必须重建系统才能使变更生效。Nix存储的符号链接是只读的——你无法直接在原地编辑它们。

bash

cd ~/.config/dotfiles
sudo darwin-rebuild switch --flake .

darwin-rebuild

has a NOPASSWD sudoers rule, so this works non-interactively.

bash

cd ~/.config/dotfiles
sudo darwin-rebuild switch --flake .

darwin-rebuild

配置了NOPASSWD的sudoers规则，因此无需交互即可运行。

The

hey

command wraps rebuilds:

bash

hey rebuild    # or: hey re
hey test       # build + activate without boot entry
hey rollback   # roll back to previous generation

hey

命令封装了重建操作：

bash

hey rebuild    # 或：hey re
hey test       # 构建并激活，不添加启动项
hey rollback   # 回滚到上一个系统版本
