yep to test it would be helpful. To setup mine, it took not long, but sure
such a facility could help. But you know, if you do not run make clean, and you
have edited usr/Makefile to not rebuild initramfs, puting your custom cpio
archive into usr and typing 'make' won't take long to rebuild the new kernel :)
I did that to get it working.

As to know if having an external archive file loaded by grub or so, I don't
know much that part of the kernel code... Hum, I really did not try to under-
stand the code involving initrd's and initramfs in init/do_mounts_initrd.c.
I wonder whether putting an executable /init in an initrd is sufficient to
have it recognized as an initramfs and not an initrd....

The important thing is /init executable script in initramfs, this is what
tells the kernel to override the "standard" way it boots.

The policy is not to have policy. It works as well in kernel design as politics.
