 Great, thanks!

 Interesting, but in looking at the earlier output I suppose this shouldn't
 be surprising...

 Other errors are due to netstat and lsof being broken, which is
 understandable given the hardening. If you have an 'is this system
 hardened' check then we can add a clause to skip the tests but otherwise
 it sounds like there's no further issues. Feel free to reopen if there's
 anything else!
