conflicts

List of modules that this module conflicts. Two conflicting modules cannot both be part of a build.

A conflicting B implies B conflicting A.

It is possible to conflict a provided feature to ensure a module is the only selected module providing a feature, but provides_unique should be used for this.

Example:

modules:
 - name: gnu_libc
   conflicts:
     - musl_libc
   # ... possible other fields
