Comment 6 for bug 1313550

Unfortunately src/xattrs.c is wholly non-existent in the precise version. So backporting xattr support would include src/xattr.{c,h} as well as inserting the calls to functions defined there throughout the rest of the code. Unfortunately that doesn't seem SRU-able. The safest way forward would be to take 1.27 into precise (which I assume is also not sru-able)
