/* Create a channel job which success depends on the success of all of
its contituents. Channel jobs are a special type of jobs that are
listed in the channel tab of Hydra and that can be suscribed.
A tarball of the src attribute is distributed via the channel.
- constituents: a list of derivations on which the channel success depends.
- name: the channel name that will be used in the hydra interface.
- src: should point to the root folder of the nix-expressions used by the
channel, typically a folder containing a `default.nix`.
channel {
constituents = [ foo bar baz ];
name = "my-channel";
src = ./.;
