by adding targets and curl wait loops to services to ensure services are not started before their depended services are reachable. Extra targets cfssl-online.target and kube-apiserver-online.target syncronize starts across machines and node-online.target ensures docker is restarted and ready to deploy containers on after flannel has discussed the network cidr with apiserver. Since flannel needs to be started before addon-manager to configure the docker interface, it has to have its own rbac bootstrap service. The curl wait loops within the other services exists to ensure that when starting the service it is able to do its work immediately without clobbering the log about failing conditions. By ensuring kubernetes.target is only reached after starting the cluster it can be used in the tests as a wait condition. In kube-certmgr-bootstrap mkdir is needed for it to not fail to start. The following is the relevant part of systemctl list-dependencies default.target ● ├─certmgr.service ● ├─cfssl.service ● ├─docker.service ● ├─etcd.service ● ├─flannel.service ● ├─kubernetes.target ● │ ├─kube-addon-manager.service ● │ ├─kube-proxy.service ● │ ├─kube-apiserver-online.target ● │ │ ├─flannel-rbac-bootstrap.service ● │ │ ├─kube-apiserver-online.service ● │ │ ├─kube-apiserver.service ● │ │ ├─kube-controller-manager.service ● │ │ └─kube-scheduler.service ● │ └─node-online.target ● │ ├─node-online.service ● │ ├─flannel.target ● │ │ ├─flannel.service ● │ │ └─mk-docker-opts.service ● │ └─kubelet.target ● │ └─kubelet.service ● ├─network-online.target ● │ └─cfssl-online.target ● │ ├─certmgr.service ● │ ├─cfssl-online.service ● │ └─kube-certmgr-bootstrap.service |

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 https://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-18.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-18.09
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
