Message definition (Nix (package manager))

In order to construct a coherent user or system environment, Nix symlinks entries of the Nix store into ''profiles''. These are the front-end by which Nix allows rollbacks: since the store is immutable and previous versions of profiles are kept, reverting to an earlier state is simply a matter of change the symlink to a previous profile. To be more precise, Nix symlinks binaries into entries of the Nix store representing the user environments. These user environments are then symlinked into labeled profiles stored in <code>/nix/var/nix/profiles</code>, which are in turn symlinked to the user's <code>~/.nix-profile</code>.

為了構建一個一致的用戶和系統環境，Nix 會將 Nix store 中的條目符號連結到 profiles 中。這是 Nix 實現回滾的前端：由於 store 是不可變的且保留先前版本的 profile，將系統還原到先前的狀態只需簡單地將符號連結更改為先前的 profile。更精確地說，Nix 將二進位檔符號連結到 Nix store 中代表用戶環境的條目中。這些用戶環境隨後被符號連結到儲存在 /nix/var/nix/profiles 中被標注的 profile，而它們則進一步符號連結到使用者的 ~/.nix-profile。
