df -k 순서 변경

df -k 하면

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda6              3020140    108924   2757800   4% /
/dev/sda1               101089     15049     80821  16% /boot
/dev/sda8             19054464     32856  18053696   1% /data
/dev/sda5              3020140     32828   2833896   2% /home
none                   2031556         0   2031556   0% /dev/shm
/dev/sda3              4032124    902020   2925276  24% /usr
/dev/sda2              4032124     57280   3770016   2% /var

여기서 /data 파티션 부분을 맨아래 /var 밑으로 내리고 싶은데....즉

머 이런 식으로 순서를 만들고 싶은데 어떻게 하면 좋을까요?

fstab과 관련이 있는 듯한데..어떻게 하면 좋을까요...?
