[Bug 1809682] Re: "systemctl enable corosync-qdevice.service" fails

[Rafael David Tinoco]

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:
