  17 # using /stretch_bootstrap to do it.  We toggle on and off the grub var
  18 # did_fai_check so we can do the check every other boot. Then
  19 # /debian_bootstrap checks for that var on boot and if we want to do a
  20 # fai check, it does it, then reboots. But fai-check also sets
  21 # did_fai_check to a 3rd state os_true which means we did the fai check,
  22 # and we don't want to do it again. This is useful for systems without
  23 # libreboot, although it's not used yet.
