Removing Old Kernels

[Jatin Davey]

Hi all

I installed ubuntu 4 weeks ago. When i had installed i was having kernel 
2.6.31-14 , then after receiving updates currently i am having 
2.6.31-16. Still i have the old kernels available in my system. I want 
to remove the old kernels and run only the latest one. If ubuntu has 2-3 
kernels just in case any of them fails then i am fine. Please also let 
me know if i am missing something. I just dont want the kernels to pile 
up after every update and increase my disk usage.

Thanks
Jatin
