The Melodic Release of ROS
I am currently hand editing the spec file generated by bloom and using an rpmlintrc file to disable some checks so these packages can build. I've built everything that would be installed with a 'ros_comm' install.
Once I have a good handle on the process, I will try to automate it with the end goal of integrating it with the standard ROS build farm.
At this time, I make no guarantees that these packages work and I wouldn't recommend using them in production at this time.
