AFAIR the initramfs code is built into the kernel, not as an option. The reason given for using a cpio archive is that it is simple and available in the kernel. The kernel itself has an initramfs built into it which is executed automatically, it's just that this initramfs is usually empty. So loading an initramfs is trivial for any kernel, and loading anything after that is handled by the initramfs. That only leaves loading the initramfs file from disk, which is handled by the bootloader along with the kernel file. -- Neil Bothwick TEXAS VIRUS: Makes sure that it's bigger than any other file.
