export bin=/system/bin
export img_path=/mnt/sdcard/external_sd
export img=$img_path/debian.img
export mnt=/data/local/debian
export loop_device=/dev/block/loop5
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
[ ! -e $mnt ] && mkdir -p $mnt
[ ! -e $img_path ] && mkdir -p $img_path

### Strings for mounting image on loop device, and configure network:

echo "Mounting the Linux Image"
mknod $loop_device b 7 0
losetup $loop_device $img
mount -t ext2 -o noatime,nodiratime $loop_device $mnt
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys

echo "Setting Up Networking"
sysctl -w net.ipv4.ip_forward=1
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf

sysctl -w net.ipv4.ip_forward=0
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
umount $mnt
losetup -d $loop_device
mount -o remount,ro -t yaffs2 $system_mount_point /system
