Hi,
The script at
http://projects.doozan.com/debian/kirkwood.debian-wheezy.sh expects a data.tar.gz archive inside the debootstrap deb. Unfortunately, it appears to be xz-compressed nowadays.

22:58:19 (535 KB/s) - `debootstrap.deb' saved [56258/56258]
x - debian-binary
x - control.tar.gz
x - data.tar.xz
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Read 3608 bytes from data.tar.xz
tar: Error exit delayed from previous errors
mv: cannot stat `./usr/sbin/debootstrap': No such file or directory
mv: cannot stat `./usr/share/debootstrap': No such file or directory

Furthermore, the version of tar shipped on my device doesn't support xz, nor is the standalone executable available.
Cheers,
Alexandre
