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 sho= uld 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 machin= e on which the kernel and world has been built since this machine is in most security appl= iances not the machine the binaries are running on! So I guess this is definitely somethin= g 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 governme= nt hiding such informations is a feature that is explicitely or part of a catalogue of asp= ects to meet. --Sig_/IloAHA9NlUaregQxepvlLSH Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWKz+8AAoJEOgBcD7A/5N8DZ8IAI6Gk54ScyN3gtzlca7yQPgF TPcqz3XWR+6BDQqY6Yt+yGa7JMwEof0VFQaEs3F++0EJnv7xbbLPuNBzWRnjfScQ MT0udG/cSe6OSO34Nf/u6qt80DiB7M3u9rMNnJjCvE8F+f+4bKykaXCfg3IOwchs h2mGTqLU7vyWfeQ33wKnBnJ9hpCqeg2b2q9AjqHTdmSD/Q8w4zID2DlOyaI8P6Fx id0wk826tt0sYyjznFOMtNpXRKyAKq9iFhVFIAaH7qqG16sm9iqlelxn8uSmUzZe UDZYec1xZ4viRgUIIq3/2t4lel7iazMWj1jz0Vs2Efycr6VN5pbkGYSV+LRHNGg= =Si6v -----END PGP SIGNATURE----- --Sig_/IloAHA9NlUaregQxepvlLSH--
