在 /usr/bin man 文档中“未在本地安装”是什么意思

Question

Linux 文件系统层次结构文档 ( man hier) for/usr/bin说：

/usr/bin
    This is the primary directory for executable programs.
    Most programs executed  by  normal  users which  are not
    needed for booting or for repairing the system and which
    are not installed locally should be placed in this
    directory.

是什么«未在本地安装»是什么意思？

Answer 1

它指的是不属于（例如，Debian）打包系统的程序，例如，您可能会编译并希望放入目录而不干扰其他程序的程序。通常那些（本地安装的）程序进入/usr/local.
