It was my fault. I modified the config directory to a relative path.

(I maintain ejabberd in Debian.)

Could you please be more specific? I'd like to get more details on this two points:

1) What do you mean precisely by saying "I modified the config directory to a relative path."? Where and what exactly did you modify?

2) If you state it was your fault, what needs to be fixed? I mean, provided you will give an exhaustive reply to the previous question, how do you think the ejabberd installation scripts should be fixed?
