Hello All,
I am trying to build a custom initrd using the busybox. In my initrd I
have modified the /sbin/init to a init script which I am mentioning below,
#!/bin/sh -e
# Set up filesystem as root and pivot into it.
export PATH
insmod /lib/uhci-hcd.ko
insmod /lib/ohci-hcd.ko
insmod /lib/ehci-hcd.ko
insmod /lib/mbcache.ko
insmod /lib/jbd.ko
insmod /lib/ext3.ko
insmod /lib/scsi_mod.ko
insmod /lib/sd_mod.ko
insmod /lib/libata.ko
insmod /lib/ata_generic.ko
insmod /lib/ata_piix.ko
insmod /lib/scsi_wait_scan.ko
insmod /lib/sg.ko
rmmod scsi_wait_scan.ko
insmod /lib/e1000.ko
mount /proc
umount initrd 2>/dev/null || true
mount -t tmpfs -o size=100M tmpfs /
umount /proc
cp -a $(ls -1 / |grep -v '\(lost+found\|mnt\|proc\)') /mnt
cd /mnt
mkdir proc
mount /proc
/bin/bash --login
I burnt an ISO image in a CD with this initrd and Kernel image, when I
tries to boot using the CD I am getting the following logs on the kernel
and in last my Kernel gives the Panic.
