Types

type Cleanup

type Cleanup interface {
	CleanupFunc(multistep.StateBag) error
}

Cleanup is an interface that some steps implement for early cleanup.

type Communicator

type Communicator struct {
	Chroot     string
	CmdWrapper common.CommandWrapper
}

Communicator is a special communicator that works by executing commands locally but within a chroot.
