This git-repo contains the files needed to create accompanying RPM files for CentOS/RHEL8 (el8), but they should work for Fedora, Alma Linux, Rocky Linux, etc. also.
Based on the inadyn version provided on https://github.com/troglobit/inadyn
The compiled SElinux policy module should also work on Fedora, and maybe even earlier versions of CentOS.
A complete version of the resulting RPM file can be found in my technoholics-repo. It can be found here: https://dev.techno.holics.at/technoholics-repo/
