That's of no consequence, because any report we would publish publically would never link the hardware to the software to the file system. All there would be is a count of 500 people using ZFS with certain settings, with absolutely no indication of who they are. Furthermore, unless you get a link to a profile, you have no way of ascertaining that link. If you share a profile link, then you lose anonymity anyways. I can't protect the privacy of people who don't want it ;) -Yaakov -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
