I'm not exactly sure how to do this... could you give me an example? My existing initrd is /boot/initrd-2.4.22-1.2140.nptl_30.rhfc1.at.img so I'm attempting: # mkinitrd --preload raid5.o /boot/initrd-2.4.22-1.2140.nptl_30.rhfc1.at.img 2.4.22-1 I'm getting a usage error and I'm evidently not understanding mkinitrd's man page.
