Hi Antoine,
Thanks for pointing out the error in my approach for asking help from other
uml users in the forum. I am using Ubuntu 10.04 as my host OS ,
linux-2.6.24-rc7 as my kernel image for uml and Ubuntu-Maverick root
filesystem(ext4 types) as rootfs for uml.
Please help me in my efforts and since this is my first post to any
forums/threads please excuse me for any lack of details provided.
Regards,
Sarthak Dash
