I have a liveCD ubuntu Linux iso image. I need to update the kernel of this image. I've tried to get the iso on a host Ubuntu system and move the compiled kernel and the modules from there to the liveCD but after doing that, the system stuck at:
loading kernel /casper/vmlinuz.. done loading file /casper/inited.img.. done
I think that the initrd can't find the root filesystem which is at "/casper/filesyste.squashfs".
Does anyone know a valid way to do this task? my next attempt would be to mount the root filesystem of liveCD on the host system and compile the new kernel from there.
