Ok, thanks for the additional explanation. The proposal you made works
for me, especially since Debian is doing the same.

Me too. What was confusing me is that both the init script *and* the
ejabberdctl script were reading it. But you gave some good explanation
for that.

The change to start the service even if the stop failed. But that's
a minor detail.

Therefore, I've applied the patch as is. Thanks again for this
contribution and the additional explanations!
