In /etc/fstab, the last two numbers have specific meanings:

1. The second-to-last number (5th field) is for dump utility (0 disables, 1 enables)
2. The last number (6th field) is the fsck order:
   • 0 = do not check
   • 1 = check first (typically used for root filesystem /)
   • 2 = check after root filesystem

The standard practice is:

• Use 1 for the root partition (/)
• Use 2 for all other regular partitions
• Use 0 for special filesystems (proc, tmpfs, swap)
