| 2–5 | Sorry for not catching this during the original review. We avoid adding "All rights reserved" to new copyright notices - would you be willing to remove this one, since you're the only copyright holder? | |

| 72 | It's best to use the lower case names, since those are the names used internally by FreeBSD (reported by uname and so on). You could add a link to arch(7) in the SEE ALSO section. | |
