问题描述
多年来，我一直在使用安装在/usr/local/texlive中的MacTeX，最近开始使用Homebrew来管理某些软件包(尽管还不是-但还是TeX ).由于采用了Homebrew，我将所有/usr/local的所有者更改为Me:admin(从root:wheel).
For years I have been using MacTeX which installs in /usr/local/texlive, and have recently started using Homebrew to manage some packages (though not — yet — TeX). As a consequence of the adoption of Homebrew, I've changed the owner of all of /usr/local to Me:admin (from root:wheel).
此所有权变更是否安全? texlive需要由root拥有吗?
Is this change of ownership safe? Is there a reason that texlive needs to be owned by root?
推荐答案
通常usr/local由root:wheel拥有，以便多个usr可以访问它，因此默认情况下，安装到它的所有内容都由root:wheel拥有.自制程序采取了一种非常不寻常(但很方便)的步骤来颠覆这一点.它说，看起来这台计算机仅由一个用户使用，所以我让她控制usr/local.这样做是为了
Normally usr/local is owned by root:wheel so that multiple usr's can access it, so by default everything installed to it is owned by root:wheel. Homebrew takes the rather unusual (but convenient) step of subverting this. It says, look this computer is just being used by one user, so I'll give her control of usr/local. It does this to
- 使所有unixy安装都更有可能为您工作
- 使它更安全(如果有其他用户在使用计算机)-作为自制用户，如果出现问题，您只能通过自制来破坏自己的帐户.
当您在自制软件之前安装tex时，它具有root:wheel所有权，这与texlive无关，并且与usr/local的正常使用有关.如果您将其权限更改为Me :: admin，则只有您可以使用texlive-我就别管它了:)
As you installed tex before homebrew it has root:wheel ownership, this has nothing to do with texlive, and everything to do with the normal usage of usr/local. If you change its permissions to Me::admin, then only you will be able to use texlive - I'd just leave it alone :)
