How-to chroot into Debian

• bzip2
• tar
• busybox binary to replace missing tools
• debootstrap-0.3.3.1 uclibc powerpc version

1. Copy the bzip and tar utilities to /mnt/HD_a2. E.g., on a linux machine, extract the utilities with tar xjf bzip2-1.0.3.tar.bz2 and tar xjf tar-1.15.92.tar.bz2, and then use ftp to transfer the extracted binaries and set executable permissions on them.
2. mkdir /mnt/HD_a2/work && cd /mnt/HD_a2/work
3. Copy debootstrap-0.3.3.1_uclibc_powerpc.tar.bz2 to /mnt/HD_a2/work/
4. ln -s /mnt/HD_a2/bzip2 /mnt/HD_a2/bzcat
5. /mnt/HD_a2/bzcat debootstrap-0.3.3.1_uclibc_powerpc.tar.bz2 | /mnt/HD_a2/tar -xvf -
6. export DEBOOTSTRAP_DIR=`pwd`/usr/lib/debootstrap
7. Copy and extract busybox-1.00.tgz and add extracted bin and sbin directory to a PATH. For example, use ftp to copy the file to /mnt/HD_a2, and then:
   1. cd /mnt/HD_a2 && gunzip -c busybox-1.00.tgz | /mnt/HD_a2/tar -xvf -
   2. export PATH=/mnt/HD_a2/bin:/mnt/HD_a2/sbin:$PATH

Note: Before proceeding to the next step, you must have internet access from the DSM-G600. If the next step fails, rm -rf /mnt/HD_a2/debian and try replacing “etch” with “sarge” in the command below.

1. /mnt/HD_a2/bin/sh /mnt/HD_a2/work/usr/sbin/debootstrap --arch powerpc etch /mnt/HD_a2/debian http://archive.debian.org/debian. Use an appropriate Debian mirror or (preferably) an apt proxy. See this article on using debootstrap.
2. cp /etc/resolv.conf /mnt/HD_a2/debian/etc/resolv.conf
3. cd /
4. mount -t proc proc /mnt/HD_a2/debian/proc
5. chroot /mnt/HD_a2/debian /bin/bash
6. apt-get update
7. apt-get install locales
8. dpkg-reconfigure locales
9. passwd root
10. apt-get install dropbear
11. apt-get install hotplug

Once Debian has been installed as per the above procedure, the next time the unit is restarted, just do the PATH export and the chroot to enter Debian.
