Linux Gurus only

This is my current environment:

[root@master ImageMagick-5.4.7]# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda2 30233928 140460 28557656 1% /
/dev/hda1 46636 4408 39820 10% /boot
/dev/hda6 2071384 377536 1588624 20% /home
none 256592 0 256592 0% /dev/shm

/dev/hda7 256667 25356 218059 11% /var


I want to add the / to the /home partion because i want all my free space available for my /home


What to do without deleting partitions?
