We did find out that we still lack some important providers in FreeBSD so some of the examples won't work but it should still be useful. BTW, stuff like the NFS provider should not be difficult to finish but given that our implementation is not related to the Solaris one it does require at least adding probes to our code. Just something to investigate in the future ;). Cheers, Pedro.
