I wrote the initrd hint for the Linux from Scratch. I have followed the initrd.txt exactly to the letter. The problem I have noticed is with one of the commands, and I checked other mkinitrd scripts and they have the workaround in it.
According to initrd.txt the echo 0x301 >/proc/sys/kernel/real-root-dev is for the old change root mechanism, but I have tried to elminate that from my script and it fails everytime saying it can't find the root, the infamous Kernel panic: VFS: Unable to mount root fs on xx:xx. Here is my linuxrc script that is built from my mkinitrd script which can be viewed at http://cvs.jg555.com/viewcvs.cgi/scripts/system/mkinitrd.
I use busybox for my script so I can keep the size down. My current size is only 387k.
#!/bin/sh
echo "Initial RAMDISK Loading Starting..." insmod /lib/megaraid.ko insmod /lib/aic7xxx.ko insmod /lib/uhci-hcd.ko echo "Mounting proc..." mount -n -t proc none /proc echo 0x0100 > /proc/sys/kernel/real-root-dev echo "Mounting real root dev..." mount -n -o ro /dev/sda2 /new_root echo "Running pivot_root..." pivot_root /new_root /new_root/initrd if [ -c initrd/dev/.devfsd ] then echo "Mounting devfs..." mount -n -t devfs none dev fi if [ $$ = 1 ] then echo "Running init..." exec chroot . sbin/init dev/console 2>&1 else echo "Using bug circumvention for busybox..." exec chroot . sbin/linuxrc dev/console 2>&1 fi echo "Initial RAMDISK Loading Completed..."
