Yeap, I created my own service, and added to the default bundle (bad thing I remove my code since I thought that was just plain impossible)... I'll try your suggestion as soon as having some time to try it out. An yes, I was not finding any way for rtorrent to grab my ~/.rtorrent.rc, even by specifying it though the command to execute, hehe. Similar things happened with other screen sessions, but I can't remember all cases, just the last one I tried (rtorrent screen session).

It would be interesting to see if s6 itself can offer such functionality out of the box though, :)

Thanks a lot !
