Then all users but 'uucp' can't operate with 'cu' on the device owned by 'uucp'. The s-bit in the owner rights indicates that the 'cu' always operate as user 'uucp' regardless of which user it has started and therfore has the permisson for this device. May be we can talk about the reason for s-bit in the group rights.
