20 Usage: ${0##*/} [-h|--help]
21 fai kexec from upstream live cds, i.e. curl|bash
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.
26 This has been tested on trisquel belenos and ubuntu xenial & 18.10.
27 With 18.10 on an x200, kexec was unreliable, resulting in freezes and
30 If the screen just sits in a weird color inverted, corrupted looking state,
31 it's probably nothing wrong with the computer, but a problem
32 with the fai server. If you can do this from a virtual terminal,
33 it will print out more info (I know from running it on a vm).
