Hi All, I am trying to boot Ubuntu Kernel using custom root file system. I am using Busybox's (Version 1.7.0) init for initing my box. I am observing init is not remounting my system root which is /dev/sda2 in my case on /. After booting up I observe it has mounted /dev/root on /, which is also working fine for me. But I want it should remount the system root (/dev/sda2 ) on /. I am writing my init script which kernel is executes during init process, and the output of the mount command just let me know if I am missing something there.
My Init file looks like that: #!/bin/nash mount -t proc /proc /proc setquiet echo Mounting proc filesystem echo Mounting sysfs filesystem mount -t sysfs /sys /sys echo Creating /dev mount -o mode=0755 -t tmpfs /dev /dev mkdir /dev/pts mount -t devpts -o gid=5,mode=620 /dev/pts /dev/pts mkdir /dev/shm mkdir /dev/mapper echo Creating initial device nodes mknod /dev/null c 1 3 mknod /dev/zero c 1 5 mknod /dev/systty c 4 0 mknod /dev/tty c 5 0 mknod /dev/console c 5 1 mknod /dev/ptmx c 5 2 mknod /dev/rtc c 10 135 mknod /dev/tty0 c 4 0 mknod /dev/tty1 c 4 1 mknod /dev/tty2 c 4 2 mknod /dev/tty3 c 4 3 mknod /dev/tty4 c 4 4 mknod /dev/tty5 c 4 5 mknod /dev/tty6 c 4 6 mknod /dev/tty7 c 4 7 mknod /dev/tty8 c 4 8 mknod /dev/tty9 c 4 9 mknod /dev/tty10 c 4 10 mknod /dev/tty11 c 4 11 mknod /dev/tty12 c 4 12 mknod /dev/ttyS0 c 4 64 mknod /dev/ttyS1 c 4 65 mknod /dev/ttyS2 c 4 66 mknod /dev/ttyS3 c 4 67 echo Creating block device nodes. mkblkdevs echo "Loading usbcore.ko module" insmod /lib/usbcore.ko echo "Loading uhci-hcd.ko module" insmod /lib/uhci-hcd.ko echo "Loading ohci-hcd.ko module" insmod /lib/ohci-hcd.ko echo "Loading ehci-hcd.ko module" insmod /lib/ehci-hcd.ko mount -t usbfs /proc/bus/usb /proc/bus/usb echo "Loading mbcache.ko module" insmod /lib/mbcache.ko echo "Loading jbd.ko module" insmod /lib/jbd.ko echo "Loading ext3.ko module" insmod /lib/ext3.ko echo "Loading scsi_mod.ko module" insmod /lib/scsi_mod.ko echo "Loading sd_mod.ko module" insmod /lib/sd_mod.ko echo "Loading sg.ko module" insmod /lib/sg.ko echo "Loading libata.ko module" insmod /lib/libata.ko echo "Loading ata_generic.ko module" insmod /lib/ata_generic.ko echo "Loading ata_piix.ko module" insmod /lib/ata_piix.ko echo Waiting for driver initialization. stabilized --hash --interval 250 /proc/scsi/scsi insmod /lib/scsi_wait_scan.ko rmmod scsi_wait_scan mkblkdevs resume LABEL=SWAP-sda2 echo Creating root device. mkrootdev -t ext3 -o defaults,rw sda1 echo Mounting root filesystem. mount /sysroot echo Setting up other filesystems. setuproot echo Switching to new root and running init. switchroot echo Booting has failed. sleep -1 Output of the Mount command: [root@/] #mount rootfs on / type rootfs (rw) /dev/root on / type ext3 (rw,data=ordered) /dev on /dev type tmpfs (rw) /proc on /proc type proc (rw) /sys on /sys type sysfs (rw) /dev/sda1 on /boot type ext3 (rw,data=ordered) tmpfs on /dev/shm type tmpfs (rw) devpts on /dev/pts type devpts (rw) Thanks Rajeev Bansal ******************************************************************************** This email message (including any attachments) is for the sole use of the intended recipient(s) and may contain confidential, proprietary and privileged information.
