更改 OS X 系統文件夾的所有者是否安全？

我正在嘗試讓 Homebrew 工作。該程序的診斷工具給了我這些建議：

你可能應該chown/usr/local/etc

…

您可能應該chown：

/usr/local/share/man/de
/usr/local/share/man/de/man1

因為這些目錄是不可寫的。我之前沒有更改過所有者或組。現在等的所有者是root，組是wheel，我的使用者名是別的。

在 OS X 上更改這些文件夾的所有者是否安全？我擔心我的使用者不會擁有所有權限，root因此其他應用程序會遇到問題，儘管我的帳戶是管理員帳戶。

以下是使該問題更易於搜尋的完整錯誤消息：

Warning: /usr/local/etc isn't writable.
This can happen if you "sudo make install" software that isn't managed by
by Homebrew. If a brew tries to write a file to this directory, the
install will fail during the link step.

You should probably `chown` /usr/local/etc

Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:

   /usr/local/share/man/de
   /usr/local/share/man/de/man1

如果這些目錄是由安裝程序（如 MacTeX 或 ImageMagick 安裝程序）或由sudo easy_install或sudo pip install.

更改這些目錄的所有者應該是安全的：

sudo chown $USER /usr/local/etc /usr/local/share/man/de{,/man1}

這顯示了按創建時間排序的 root 擁有的文件：

find /usr/local/{etc,share/man} -user root -exec stat -f '%B %N' {} \; | sort
