I run a service on my Raspberry Pi that distributes hardware random numbers to my lan. For computers that don't have a hardware RNG. Just to see what the fuss was about I converted this Pi to systemd. It worked fine. The unit files were easier to read and write.
On my desktop I run debian testing. and I converted to systemd, with out knowing it, just by doing periodic updates.
Systemd is still free software. All the source is published, and it can be forked at any time. We need this functionality. It is a good thing that it has been redesigned to work smoothly together.
If the complainers really wanted to help, they could do a security audit instead of bellyaching!
If pottering becomes unbearable, the project can be forked. A lot of powerful forces need this project to work, so I suspect it will.
Its just a lot of whining and bellyaching from people who don't want to do anything.
