Having socket-activated epmd means that there always be only a single instance managed centrally. Because Erlang also starts it automatically if not available, and in worst case scenario 'epmd' can be started by some Erlang application running under systemd. And then restarting this application unit will cause complete loss of names in 'epmd' (if other Erlang system are also installed on this host). E.g. see at which lengths RabbitMQ goes to recover from such situations: https://github.com/rabbitmq/rabbitmq-server/blame/7741b37b1efa97ac9b17685cc626bd35ee52ca16/src/rabbit_epmd_monitor.erl#L36 Having the only one socket-activated epmd completely solves this problem.
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-18.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.03
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
