i'm sure i'm going to regret asking this only seconds after i hit ENTER, but at what point during the boot process does the kernel's corresponding /boot/initrd.img file kick in and get used? i'm following along reading the logic of initramfs and early userspace, and can see where a compressed cpio archive can be incorporated into the kernel image itself. fair enough. but how does the /boot/initrd.img (which is itself a compressed cpio image) get processed during boot? it's certainly not passed as an argument to the kernel as i can see via /proc/cmdline. so how does it affect the boot sequence? thanks. rday ======================================================================== Robert P.
