I use the original disk image that comes with M5 to boot off of as hda1, and
then mount my blank image as hdb1. This has proven to work for me. Post
more questions if you get stuck.

How should I go about setting up a bootable linux setup on a raw disk
image? What is the best/easiest way to do it?

Aqeel,
I've found that just creating bare disk images by hand is easier and less
error prone for me.
http://www.osdev.org/osfaq2/index.php/Disk%20Images%20Under%20Linux
This site will walk you through how to create a bare image. You can then
mount the image and copy your executable files to it.
Add these lines to your .rcS file to mount the disk within the simulator:
echo -n "mounting file set.."
mkdir -p /z/
mount /dev/hdb1 /z/
echo "done."
Go into configs/common/FSConfig.py and add to it a second disk, it should
be
self evident as to how to do so. Just look at how the current disks are
added.
Hope this helps.

Subject: [m5-users] problem creating disk images
Hello,
I am having trouble creating images for full system simulation. I follow
the directions given at
http://m5.eecs.umich.edu/wiki/index.php/Using_linux-dist_to_Create_Disk_Imag
es_and_Kernels_for_M5
I am creating the images on a system running Ubuntu, with gcc 4.1.2.
After running "ptxdist go", I get the following compile error:
