I`ve been trying to use this image(Fedora 14 64bits) but it only has 2gb on the / (root) partition

I want to increase this because i need to install a few rpm and libs on my /var

What can i do to increase this partition to 10gb? Or how can i chance maybe my /home and /var on the image to another partition so i can successfully run my applications?

Thank you for the support!
