Please refer to RH Beaker job #6966531 for additional details.

Version-Release number
restraint-rhts-0.4.0-1

To Reproduce
Steps to reproduce the behavior:
Either:

1. Schedule a job with inst.multilib on kernel command line, or
2. in an installed system with Beaker repo, try to install restraint-rhts.i686 and restraint-rhts.x86_64 (both need to be specified in case the repo contains also packages for other architectures - because of https://bugzilla.redhat.com/show_bug.cgi?id=1996681).

Actual behavior
RHEL installation fails due to conflicting files in multilib packages.

Expected behavior
No file conflicts, system installation is successful.
