under the `kubelet` process. On systems with `journalctl` the following is an example command line
to view the last 1000 `kubelet` logs via the `less` utility to allow for `vi`-style searching:

```console
$ journalctl -t kubelet -n 1000 | less
```

The user-defined overlay uses a path spec that includes the ability to select list items by key. In the example above,
the container with the key-value "name: discovery" is selected from the list of containers, and the command line

### Brief System Overview

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a

credentials of peer sites to be identical. This is no longer necessary because STS tokens are now signed with the site replicator service account credentials, thus allowing flexibility in the independent management of root accounts across sites and the ability to disable root accounts eventually.

However, this means that STS tokens signed previously by root credentials will no longer be valid upon upgrading to the latest version with this change. Please re-generate them as you usually do. Additionally,...
