  WARNING!

  Be warned that it would appear APT does not pass it's root directory
setting on to dpkg.  Attempting to run an install with the above will
cause APT to use package sources and dependency information from
/usr/unstable/, but then invoke dpkg with the config normally used for
the system.

  As a result, my system is now running some extremely borken
combination of packages from lenny and sid.  I see a reinstall in my
near future.
