===== Installing steps =====

  - 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.
  - ''mkdir /mnt/HD_a2/work && cd /mnt/HD_a2/work''
  - Copy ''debootstrap-0.3.3.1_uclibc_powerpc.tar.bz2'' to ''/mnt/HD_a2/work/''
  - ''ln -s /mnt/HD_a2/bzip2 /mnt/HD_a2/bzcat''
  - ''/mnt/HD_a2/bzcat debootstrap-0.3.3.1_uclibc_powerpc.tar.bz2 | /mnt/HD_a2/tar -xvf -''
  - ''export DEBOOTSTRAP_DIR=`pwd`/usr/lib/debootstrap''
  - 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: 
    - ''cd /mnt/HD_a2 && gunzip -c busybox-1.00.tgz | /mnt/HD_a2/tar -xvf -''
    - ''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. 
  - ''%%/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 [[http://www.debian.org/mirror/list|an appropriate Debian mirror]] or (preferably) an apt proxy.  See [[http://www.debian-administration.org/articles/426|this article]] on using ''debootstrap''. 
  - ''cp /etc/resolv.conf /mnt/HD_a2/debian/etc/resolv.conf''
  - ''cd /''
  - ''mount -t proc proc /mnt/HD_a2/debian/proc''
  - ''chroot /mnt/HD_a2/debian /bin/bash''
  - ''apt-get update''
  - ''apt-get install locales''
  - ''dpkg-reconfigure locales''
  - ''passwd root''
  - ''apt-get install dropbear''
  - ''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.
