  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,

  23 # libreboot, although it's not used yet.
