"The purpose of a fake package is to trick dpkg and apt into believing that some package is installed" (Debian).

eqivs is a Debian package which allows to create fake packages easily.

Daraels comment in David Norths guest post on Akkana Pecks blog (Whoaaa) gives an insight how we use equivs.

We call them surrogates.

To get our surrogates clone the Darcs repository:

cd /opt
darcs clone https://at.magma-soft.at/darcs/equivs
