我需要/etc/fstab在另外两行之后安装一个特定的行:
# Always mount these first
UUID=fdf38dd4-9e9d-479d-b830-2a6989958503 / ext4 noatime,discard,errors=remount-ro 0 1
UUID=2b548eb8-fa67-46ce-a998-91d587dba62f /home/.hdd ext4 errors=remount-ro 0 2
# Always mount this second
none /home/ak aufs br:/home/.ssd/ak=rw:/home/.hdd/ak=rw 0 0

当前的行为是经常以不可预测的方式颠倒最后两行的顺序。如何指定必要的顺序?
