type RevertCompoundError

type RevertCompoundError interface {
	Error() string
	Unwrap() []error
}

type RunState

type RunState struct {
	// Start is true if fsu is successfully started.
	Start bool
	// ExitCode is the value returned by shim.
	ExitCode int
	// WaitErr is error returned by the underlying wait syscall.
