Need to create a bootable CD of my current system (easy method)
 

I am doing a bare metal restore onto a dissimilar system and it requires me to update the hardware, etc. To do this I need to run linux rescure and then run mkinitrd to create the new .img. The issue that I have run into is different versions of the rescue CD and the system. When I try to run mkinitrd on a linux rescue that is version 2.6.18-262.e15 and the system has only /lib/modules/2.6.18-274.e15 it returns with a no modules found message. I was able to successfully do this on another system when the versions where the same. I had to use the syntax mkinitrd -v -f /boot/initrd-2.6.18-274.e15 $(uname -r) to get it to work, versus mkinitrd -v -f /boot/initrd-2.6.18-274.e15 2.6.18-274.e15 which returned no modules found.

I can't change my bare metal restore method and need to find a way to create a linux rescue CD that has 2.6.18-274.3.1.e15 for my next BMR, so I can run the mkinitrd to change the .img for the new hardware.

Anyways any help would be appreciated.

I can't quite follow what your doing, but take a look at remastersys it may help.
