Debian Installation on Kindle Touch
 Setting up Base Image
dd if=/dev/zero of=/tmp/debian.ext3 bs=1M count=1280 mkfs.ext3 /tmp/debian.ext3 tune2fs -i 0 -c 0 /tmp/debian.ext3 mount -o loop -t ext3 /tmp/debian.ext3 /mnt/debian
 If host architecture is same as target architecture
Debootstrap a basic debian on to your image if your PC has armel architecture too.
debootstrap --arch=armel testing /mnt/debian http://ftp.us.debian.org/debian
 If host architecture is different from target architecture
debootstrap --arch=armel --variant=minbase --foreign jessie /mnt/debian http://ftp.us.debian.org/debian
Later, when you are on Kindle and when you have set up the chroot environment you have to start the second stage of the base installation:
UPDATE: Currently, "testing" is the Debian Sid release. Debootstraping it and Chrooting on a kindle will result in FATAL: KERNEL TOO OLD. To fix this replace "testing" with "wheezy" or "jessie". NOTE: Using the argument --variant=minbase will significantly reduce the size of the debian installation.
 Copy Image to Kindle
 Setup Chroot Environment
mount -o loop -t ext3 /mnt/base-us/debian.ext3 /mnt/debian mount -o bind /dev /mnt/debian/dev mount -o bind /dev/pts /mnt/debian/dev/pts mount -o bind /proc /mnt/debian/proc mount -o bind /sys /mnt/debian/sys cp /etc/hosts /mnt/debian/etc/hosts
Note: Quite a few people reported lock-ups when using apt-get with debian.ext3 mounted from /mnt/us and also seriously bricking the Kindle. Therefore /mnt/base-us is used here. This seems to be safe as long as userstore is not used as USB drive. Another option would be to Repartition the Kindle.
 Continue Installation
If you created debian.ext3 on a non-armel architecture:
 Usage of Chroot Debian
 Getting a Chroot Shell
chroot /mnt/debian /bin/bash
Once you added a user to the Debian system you can login with that user account:
chroot /mnt/debian /bin/login
 Other options
In case you want to have access to userstore from debian execute before chrooting:
mount -o bind /mnt/us /mnt/debian/mnt/us
