Bug#700844: Add support for running multiple instances

[Ondřej Surý]

Package: mumble-server
Version: 1.2.3-349-g315b5f5-2.2
Severity: wishlist
Tags: patch

Hi Ron,

this init.d file adds an initial support for running multiple
instances of murmurd.  The package will need some more changes to
successfully enable this, and it will be post-wheezy work, but I would
like to use this bug to track all the needed changes.

TODO:
- Move /etc/mumble-server.ini to /etc/mumble-server/mumble-server.ini in 
{post,pre}{inst,rm}
