Hi,
the debian tor package maintainer implemented the multi-instance feature request [1][2][3]. Thanks Peter!
If you want to learn more about it, have a look at tor-instance-create(8):
https://gitweb.torproject.org/debian/tor.git/tree/debian/tor-instance-create...
Once tor 0.2.7.x stable is release I'll start playing with it and change ansible-relayor [4] to make use of that new functionality on debian systems by default - instead of implementing it via the ansible role itself (current behavior).
We have quite good multi-instance support across multiple systems now (Fedora, CentOS, Debian, OpenBSD). FreeBSD is still somewhat of a hack - but it works as well.
