Howto create a Debian chroot on an Android phone

This page will grow once I have everything running, but this is a starting point:http://www.android-hilfe.de/anleitungen-fuer-motorola-milestone/26870-ho…

1. [HTC Desire, unbranded, European version]: Flashed (pre-rooted and with busybox included) firmware from http://android.modaco.com/content/htc-desire-desire-modaco-com/315108/04…, taking file 2.09.405.8-update-bravo-stock-rooted-busybox-withradio-signed.zip
2. On a Debian squeeze (amd64, but with i386 it will be similar) box:
   1. sudo apt-get install debchroot qemu-user
   2. Download qemu-arm-static from http://packages.ubuntu.com/lucid/qemu-arm-static (and its dependency) to get the build-arm-chroot script
   3. dd if=/dev/zero of=debian.img bs=1024 count=1950000
   4. sudo mkfs.ext2 -F debian.img
   5. sudo tune2fs -c0 debian.img
   6. mkdir debian
   7. sudo mount -o loop debian.img debian/
   8. sudo build-arm-chroot –verbose –arch=armel –foreign squeeze debian http://ftp.de.debian.org/debian
   9. sudo mkdir debian/sdcard
   10. sudo mount -t proc none debian/proc/
   11. sudo mount -t sysfs sysfs debian/sys/
   12. sudo mount -t devpts devpts debian/dev/pts
   13. sudo chroot debian/ /bin/bash
   14. export HOME=/root
   15. export USER=root
   16. export LC_ALL=C
   17. echo ‘deb http://ftp.de.debian.org/debian squeeze main contrib non-free’ > /etc/apt/sources.list
   18. aptitude update
   19. aptitude install –without-recommends lxde tightvncserver xfonts-base
   20. [optional, this is my personal package selection]: aptitude install psmisc nmap aircrack-ng ruby1.8 rubygems driftnet wireshark tshark subversion openssh-client openssh-server git
   21. aptitude clean
   22. echo localhost > /etc/hostname
   23. echo ‘nameserver 4.2.2.2’ > /etc/resolv.conf
   24. to create VNC server startup files (setting connect password, I used password ‘debian’):
       [for HTC Desire]: vncserver -geometry 800×480
       [for Motorola Milestone]: vncserver -geometry 854×480
   25. sed -i ‘s/\/etc\/X11\/Xsession/lxsession/’ /root/.vnc/xstartup
   26. echo > /usr/sbin/lxde <<EOF
       #!bin/sh
       export USER=root
       vncserver -geometry 800×480
       EOF
   27. chmod +x /usr/sbin/lxde
   28. echo > /usr/sbin/klxde <<EOF
       #!/bin/sh
       killall Xtightvnc && killall lxsession
       EOF
   29. chmod +x /usr/sbin/klxde
   30. killall /usr/bin/qemu-arm-static
   31. exit
   32. sudo umount debian/proc
   33. sudo umount debian/dev/pts
   34. sudo umount debian/sys
   35. sudo umount debian/
3. Copy this debian.img file to the SD card under a newly created folder “debian”.
4. Copy the startdeb and stopdeb scripts to the same “debian” folder.
5. Deactivate the hard disk mode so that the SD card is again available to Android running on the phone.
6. On the mobile phone (e.g. via a “local” shell with ConnectBot or with “adb shell” from the connected Debian box):
   1. mkdir data/local/debian
   2. mkdir data/local/debian/mnt
   3. sh /sdcard/debian/startdeb
   4. lxde
   5. Use any local VNC client to connect to localhost, port 5091 using the password set previously
   6. klxde
   7. sh /sdcard/debian/stopdeb
