Well, well, this gets now out of hands and I do not want to be bothered by this law gibberish. I understand the importance of Copyright notes and the world should definitely know that I/we are using FreeBSD as our platform and not a commerical UNIX or even Linux, but there are some minor aspects I wish not to float around the world. I do not want to hide the copyright notes. I simply want to hide the machine on which the kernel and world has been built since this machine is in most security appliances not the machine the binaries are running on! So I guess this is definitely something worth to hide, since "uname(8)" reveals informations someone wants to hide. Second, it is, for the impact of skript kiddies, somehow of use to hide the OS' revision/version. And by the way, in some areas within the structure of companies or government hiding such informations is a feature that is explicitely or part of a catalogue of aspects to meet.
