1.15. /root

这是系统管理员 'root' 的家目录。这可能有点令人困惑(“root 在 root 下”),但在以前,'/' 是 root 的家目录(因此得名管理员帐户)。为了使事情更整洁,'root' 有了自己的家目录。为什么不在 '/home' 中?因为 '/home' 通常位于不同的分区甚至另一个系统上,因此当由于某种原因仅挂载 '/' 时,'root' 将无法访问它。

FSSTND 仅仅说明这是 'root' 家目录的推荐位置。最终用户可以自行决定 'root' 的家目录。 但是,FSSTND 也指出:

	  
  If the home directory of the root account is not stored on the root
  partition it will be necessary to make certain it will default to 
  / if it can not be located.
  
  We recommend against using the root account for tasks that can be
  performed as an unprivileged user, and that it be used solely for 
  system administration. For this reason, we recommend that subdirectories
  for mail and other applications not appear in the root account's home
  directory, and that mail for administration roles such as root, postmaster,
  and webmaster be forwarded to an appropriate user.
