Investigate reducing package dependencies #82

Open bgilbert opened 6 years ago

bgilbert commented 6 years ago

Fedora packages often include a fairly expansive set of dependencies, some of which may not be needed in Fedora CoreOS. Investigate reducing the set of package dependencies pulled into the OS image.

Many people have tread a similar path before so it may be good to gather input from others.

A couple of options include:

reducing dependencies in source rpm packages
converting dependencies to recommends rather than hard requires in source rpm packages
using some sort of dependency whiteout mechanism where we explicitly say "we know this is a dependency and we know we don't want it"

For what it's worth, I was just looking at this, simply out of curiosity, and generated the attached dependency graph for the binary RPMs. It should be more or less complete except that it filters out the 196 language-specific glibc-langpack packages. Maybe browsing through the graph will provide some ideas? For example, considering the mission, does FCOS need cracklib?
