Yep. My 2 cents -- 'add' and 'attach' are so similar the words that I think that ZFS tools UI designers (if any) should re-consider naming of these commands. Or 'add' command should always be interactive and ask for at least two confirmations that a user knows what he is doing and why. Perhaps, it should include a ZFS micro-exam too. Jokes aside, this is too easy to make a mistake with the consequences that are too hard to correct. Anyone disagrees? -- Andriy Gapon _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
