 Basically every relay operator who wants to make use of available system
 ressources (CPU, RAM, bandwidth) has to run multiple tor instances on a
 single host, but the current init script does not include such a feature
 and everyone who needs it has to hack something togheter on their own.

 This ticket is about modifying/extending /etc/init.d/tor (shipped with
 your debian packages) to allow for easy multi-tor instance handling.

 The idea is to introduce an new boolean "MULTI_INSTANCE" in
 /etc/default/tor

 If MULTI_INSTANCE is set to "yes" the init script would start a tor
 instance per every available
 *.torrc file in /etc/tor, in all other cases proceed as usual (current
 behaviour).
 This allows for an easy and transparent transitioning.

 If this is acceptable to you I would go ahead and implement it based on
 this script that is currently used by torservers:
 https://gist.github.com/7adietri/9122199
 https://www.torservers.net/wiki/setup/server#multiple_tor_processes

 but doesn't include the opt-in (MULTI_INSTANCE boolean) yet.
