These are all packages that I stopped using and hence just create noise
in my inbox for each change affecting them and let's face it, while I
still enjoy contributing to nixpkgs, it doesn't really make sense to be
listed there if I can't do much anyways.
Each of these packages can be taken over by someone or removed if
people think that's reasonable.
Of course, if other maintainers face issues, I can answer some questions
if needed & possible.
Basic test which confirms new inputs can be created and that messages
can be sent to a UDP-GELF input using `netcat`.
This test requires 4GB of RAM to avoid issues due insufficient
memory (please refer to `nixos/tests/elk.nix` for a detailed explanation of
the issue) for elasticsearch.
Also it's ensured that elasticsearch has an open HTTP port for communication
when starting `graylog`. This is a workaround to ensure that all services
are started in proper order, even in test environments with less power.
However this shouldn't be implemented in the `nixos/graylog` module as
this might be harmful when using elasticsearch clusters that require e.g.
authentication and/or run on different servers.
