os-prober                Utility to detect other oses on a set of drives

Come abbiamo potuto osservare, wajig è molto più "diretto" dei suoi compagni; basta scegliere il comando appropriato e apporlo dopo wajig per effettuare l'operazione richiesta, comodamente descritta dall'aiuto del comando stesso (v. sopra).
