当我退出 ssh 会话时如何停止 umount all？

Question

因此，当我通过 ssh 登录 Lucid 并键入exit以结束会话时，umount -a系统会首先运行该命令。在系统将我注销之前，我看到了以下消息：

umount: /home: device is busy.
    (In some cases useful info about processes that use
     the device is found by lsof(8) or fuser(1))<p>
umount: /var/run: device is busy.
    (In some cases useful info about processes that use
     the device is found by lsof(8) or fuser(1))<p>
umount: /dev/shm: device is busy.
    (In some cases useful info about processes that use
     the device is found by lsof(8) or fuser(1))<p>
umount: /dev: device is busy.
    (In some cases useful info about processes that use
     the device is found by lsof(8) or fuser(1))<p>
umount: /: device is busy.
    (In some cases useful info about processes that use
     the device is found by lsof(8) or fuser(1))<p>

我怎样才能阻止这种情况？

Answer 1

然而，似乎它根本没有卸载文件夹。

好吧，让我们读一下“man on_exit”手册页，也许您登录的机器上的某些配置正在和您作对。
