The people who are most against systemd are the serious, professional, often long-time Linux system administrators who have to provision and maintain production Linux systems.
Says the anonymous coward.
Balls.
Every single claim pretending to be from "serious, professional, often long-time Linux system administrators" has turned out to be a joke.
People who claim to have thousands of VMs running mongoDB who are unable to debug a 300 line init script,
People who claim to have huge problems but have never made a bug report.
People who claim that they have made a bug report but some evil person made it disappear, but are unable to provide any proof.
People who claim that they've moved en-masse to FreeBSD because they don't like monolithic systems, but appear to know nothing about FreeBSD.
People who are all Anonymous Cowards.
People who never engage with anyone who will try to fix their problems.
Because there are no such people. They are all simple trolls.
