 In 13.2.0 build 3, the generated contents manifest comes with an 'x'
 attribute for /usr/bin/ping listing the one xattr that the file has

 This has appeared as a result of setting ping as suid root (#12427). I
 can't explain why setting the suid bit causes the xattr to appear in the
 manifest, and without suid the xattr doesn't get detected/listed, but I've
 double checked, and this is what is happening.

 This is further complicated by the fact that fv (the implementation of
 olpc-contents-verify) regards 'x' as bad data, causing a contents manifest
 failure on olpc-update to this new build. As fv has been shipped for a
 long time now, this means that we cannot support the 'x' attribute until
 we make a backwards-incompatible change in the manifest format to
 officially add this.
