The original poster wanted a setup where the initrd was NOT part of the kernel, which begs the question of how/where it would be put into flash so something could load/uncompress it. I'd love to have a way to decouple the two so i wouldn't have to recompile the kernel when i change the root image, but still not waste any space in flash. I guess they could be written one after the other and the loader is just given a "load map" of where each one resides. Would this satisfy Krishnakumar's requirements? Tibor
