In this system, if I'm not mistaken, there are no pre-depends. If a package
pre-depends on another, that means that is level is higher so the package it
predepends on will be automatically installed before.
Conflicts and replaces have not the same function as the dependencies. The
tree is built with the dependencies. The other fields are handled using this
tree, but are not mirrored in it.

Since level 1 is installed before level 2, B which is level 1 will be
installed automatically before C (which is level 2). There is no more
distinction needed.
