fstab 中的 fsck 部分是什么？

我对 fsck 实用程序有基本的了解，但是 /etc/fstab 中的“fsck”部分表示什么？它的值为 0、1、2，这些值是多少？

谷歌搜索显示 0- 不会被检查 1- 将在启动时检查 2- 现在它是什么？

从fstab(5)手册页：

   The sixth field (fs_passno).
          This field is used by the fsck(8) program to determine the order
          in which filesystem checks are done at reboot  time.   The  root
          filesystem  should be specified with a fs_passno of 1, and other
          filesystems should have a fs_passno of 2.  Filesystems within  a
          drive will be checked sequentially, but filesystems on different
          drives will be checked at the same time to  utilize  parallelism
          available in the hardware.  If the sixth field is not present or
          zero, a value of zero is returned and fsck will assume that  the
          filesystem does not need to be checked.
