// leaves claim containment groups alone (it seeds and sweeps around them,
// flag off included), and it knows them only by their name. The name's
// format has one definition, in internal/cgroup, and every name this
// package makes must read as one there, both as the containment's host name
// and as its exec cgroup's directory name. A plain host never does.
