=== Profiles(系统画像) ===

~~<div lang="en" dir="ltr" class="mw-content-ltr">~~

为了建构一个连贯的用户或系统环境, Nix将Nix存储库中的条目符号链接到''profile''. 这些是Nix允许回滚的"前端": 因为存储库是不可变的, 而且以前的profile版本被保留了下来, 回到更早的状态只需要简单地让符号链接指向一个先前的profile. 更精确地说, Nix将二进制文件符号链接到Nix存储库中描述用户环境的条目中. 这些用户环境随之被符号链接到<code>/nix/var/nix/profiles</code>中带有标签的profile, 而这些profile又被符号链接到用户的<code>~/.nix-profile</code>.

~~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>.
