Well, you could have zpool check if there is a valid ZFS label and prompt/warn if it doesn't find one on whatever device it's about to wipe. That doesn't fix the gmirror/gpt case, but it might make zpool more intuitive to use. -- John Baldwin _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
