This is a stop-gep way of getting a debian enviroinment on thecus systems without touching flash or a working serial cable.

1. Follow SSHBackdoor
2. Format the disks. I used fdisk + mke2fs, presumably the webui can do that as well.
3. Get cdebootstrap-static
   1. cd /tmp; wget http://nchipin.kos.to/cdebootstrap-static.tar.gz
   2. or when it gets applied upstream from debian and convert the .deb into tarball (with alien or dpkg-deb + tar czf )
4. unpack it: tar xvzf cdebootstrap-static.tar.gz
5. ln -s /tmp/usr/share/cdebootstrap/ /usr/share/cdebootstrap
6. /tmp/usr/bin/cdebootstrap etch /mnt/ http://ftp.fi.debian.org/debian
7. chroot into your debian: LD_LIBRARY_PATH=/mnt/lib /mnt/lib/ld-2.3.6.so /mnt/usr/sbin/chroot /mnt/
8. setup /etc/fstab and mount necessary filesystems, as well as /etc/apt/sources.list

Inside chroot, put in your fstab:

 devpts           /dev/pts         devpts      gid=5,mode=620   0   0
 proc             /proc            proc        noexec,nosuid    0   0
 none             /sys             sysfs       noexec,nosuid    0   0

And fill you /etc/apt/sources.list normally and /etc/resolv.conf.

Now, you can for example

• apt-get install pbuilder and run pbuilder create
