    I found this on Google but it doesn't help me much:

echo "Loading scsi_mod module"
insmod /lib/scsi_mod.o 
echo "Loading sd_mod module"
insmod /lib/sd_mod.o 
echo "Loading cpqarray module"
insmod /lib/cpqarray.o 
echo "Loading jbd module"
insmod /lib/jbd.o 
echo "Loading ext3 module"
insmod /lib/ext3.o 
mount -t proc /proc /proc
echo Mounting /proc filesystem
echo Creating root device
mkrootdev /dev/root

This seems to be where /dev/root comes from. And my kernel can't find it for some reason.



echo 0x0100 > /proc/sys/kernel/real-root-dev
umount /proc
echo Mounting root filesystem
mount --ro -t ext3 /dev/root /sysroot
pivot_root /sysroot /sysroot/initrd
