  20 Usage: ${0##*/} [-h|--help]
  21 fai kexec from upstream live cds, i.e. curl|bash
  22
  23 You can copy this to a http server, then wget -O- url|sudo bash
  24 curl is sometimes not preinstalled on a live cd.
  25
  26 This has been tested on trisquel belenos and ubuntu xenial.

  28 If the screen just sits in a weird color inverted, corrupted looking state,
  29 it's probably nothing wrong with the computer, but a problem

  31 it will print out more info (I know from running it on a vm).
