For those of you who downvote this because you think I'm being disingenuous, I speak from personal experience of working closely with Red Hat in a number of projects where their code were an integral part of the solution.

Red Hat really do reinvent the wheel, for the purpose of making money selling popular kinds of software. And they're shamelessly declaring themselves superior to the product they're mimicking. And the projects are ran like side projects of the lead developers.

And yet Systemd represents the biggest advancement for Linux in decades.
