during fedora boot, what picks up the initrd.img from /boot?
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.
