Hello Bert,

We are not yet fully disabling sysv related scripts because there are systems that are not, yet, using systemd. Not for this case, but, one of these examples is windows WSL environment, where systemd is not supported yet. Just wanted to mention this to show there are some other things to be taken in consideration when dropping support, entirely, for sysv scripts, for example.

Just a quick example on corosync running inside WSL environment:
