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.
Geoff

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:
