didn't gave any result. This is useful when using partial mirrors built by
simple-cdd while trying to build a Debian CD using a newer d-i (in my case
etch CD with lenny d-i).
* Use dpkg --fsys-tarfile instead of ar for extracting files from deb
packages. The previous invocation could have failed for packages using
something other than gzip compression.
This is made possible by allowing to include a "%ARCH%" placeholder in the
environment variables DI_WWW_HOME and DI_DIR which is expanded to the correct
value at runtime.
Supported for Etch and later.
