We did run a big piece by Jim Salter a couple of years ago on next-gen file systems that focused on ZFS and btrfs (http://arstechnica.com/information-technology/2014/01/bitrot...), but yeah, I'd love to have more filesystem-level stuff showing up. The response is generally very, very strong—turns out people really like reading about file systems when the authors know what they're talking about!

That's more complicated, unfortunately. I am not a lawyer etc etc and I am only speaking generally here, but Ars and CN own the copyright on the pieces we run (though syndications like Adam's piece today are different), and wholesale reuse of the text without remuneration isn't something that the CN rights management people like. Fair use is obviously fine, so quoting portions of pieces as sources in documentation is not a problem, but re-using most or all of something isn't (necessarily or usually) fair use.
(again, not a lawyer, my words aren't gospel, don't take my word for it, etc etc)
