1. Resolves dependencies between modules (and consider them as enabled)
2. Filter out RPMs which are in non-enabled modules (exclude, disable)
3. Install RPMs from profile

It resolves dependencies between modules and rpms at different points of time.

We have test-app rpm which depends on kkt >= 50. And we have 2 kkt build versions: 30 and 80.

And they are packed into a modules as following:

• kkt:konsky:2019:deadbeef:x86_64
  • Contains kkt-80-1.x86_64
• kkt:barani:2019:bbadbeef:x86_64
  • Contains kkt-30-1.x86_64
• test-app:master:2019:deadbeef:x86_64:
  • Contains test-app-1-1.x86_64
  • Requires kkt: []

That means, if you would be about to install test-app, you would get test-app-1-1 and kkt-80-1… But not with DNF. What you will get is:

Error:
 Problem: package test-app-1-1.x86_64 requires kkt >= 50, but none of the providers can be installed
  - conflicting requests
  - package kkt-80-1.x86_64 is excluded

Try it yourself!

$ ./build.sh
$ sudo rm -rf /var/cache/dnf/test*
$ sudo dnf --repofrompath=test,$PWD/repo module install test-app
