I wonder whether my FreeBSD servers are counted as UNIXes at all, I did run OS fingerprinting against some randomly chosen, and they don’t disclose OS ;-)

What I was trying to say is: there are some UNIX-like systems which are used by really cautious sysadmins who set things up so that even system fingerprinting can not discover what system the server is running.

Which covers over 60% of UNIX like systems mentioned on that website. I can not call them UNIXes, as many of them do not pay loyalties to be called UNIX. Incidentally, zfs and dtrace are available on FreeBSD… Just mentioning.
