Install dependencies automatically from backports.
I was wondering if apt can be configured to install the required
dependencies from backports automatically, if the dependencies can't be
fulfilled from the stable repository.
This's pretty common with Debian multimedia packages which require
packages from backports.
Notice, by default apt should not prefer installing from backports if
the required dependency can be fulfilled without using it.
This's my current /etc/apt/preferences -
Pin: release a=stable
Pin: release a=squeeze-backports
Pin: release a=testing
# not working
Pin: release o=Unofficial Multimedia Packages
Also another question which someone may like to answer is -- why am I
not able to disable the Debian multimedia repository with the above
