Use "su --command" instead Beside what others already said: As you said it is run in preinst scripts you would need to pre-depend on sudo – and you would need to discuss this first on debian-devel@ as strongly recommend by debian-policy (§3.5 and §7.2). The outcome of this discussion would probably be that you should use su… su on the other hand is 'free' to use as it is provided by the essential login package, so no dependency is needed at all.
