Bug#987104: minetest-server: Ipv6 is not enabled in default settings.

[Robert Seimetz]

Package: minetest-server
Version: 5.3.0+repack-2
Severity: normal
Tags: ipv6
Control: affects -1 + freedombox

At the moment, ipv6 support is not enabled in default settings. This
is probably because the comment in the configuration file claims that,
when ipv6 support is enabled, minetest may only listen to ipv6 requests.

I've tested the minetest client and the results show me that, when ipv6
is enabled, the minetest listens to  both, ipv4 and ipv6 requests.

I am currently using the minetest server through the freedombox package 
and it would be good if freedombox users could use minetest out of the box.
Freedombox could also set this setting, but I think all users can benefit
from it.
