  20 Usage: ${0##*/} [-h|--help] [HOST]
  21 fai kexec from upstream live cds, i.e. curl|bash
  22
  23 If HOST argument, ssh to root@HOST before doing kexec. This does what
  24 pxe would do, but skipping boot sequence up to and including the pxe
  25 dhcp.
  26
  27
  28 You can copy this to a http server, then wget -O- url|sudo bash
  29 curl is sometimes not preinstalled on a live cd.
  30
  31 Alternative to http server:
  32 1. on install machine nc -l 1234 | sudo bash
  33 2. On another machine nc INSTALL_MACHINE 1234 <live-kexec
  34 Obviously beware that anyone on your network could send commands to the install machine.
  35
  36 This has been tested on trisquel 7 & 8 & ubuntu 16.04 & 18.10.  With
  37 18.10 and trisquel 8 on an x200, kexec was unreliable, resulting in
  38 freezes and kernel panics.
  39
  40 If the screen just sits in a weird color inverted, corrupted looking state,
  41 it's probably nothing wrong with the computer, but a problem
  42 with the fai server. If you can do this from a virtual terminal,
  43 it will print out more info (I know from running it on a vm).
