Hi Arnd, Simon and Jiri,
First and foremost, thank you so much for taking the time to review my code
and for providing your comments.
I will do my best to address the issues and improve the code for the
next submission.

I will also add a longer description on why I went this route, it is mostly
due to compatibility with existing distributions of netatalk 2, which can
work without modification.

I will fix this in the next revision, I was not sure if I should touch the
appletalk code for my first submission, but I can add a third patch that
takes care of this.

Kind Regards,
Rodolfo
