+# fai_check is so we can act like a pxe boot, but just for fai, and by
+# using /debian_bootstrap to do it. We toggle on and off the grub var
+# did_fai_check so we can do the check every other boot. Then
+# /debian_bootstrap checks for that var on boot and if we want to do a
+# fai check, it does it, then reboots. But it also sets did_fai_check to
+# a 3rd state os_true which means we did the fai check, and we don't
+# want to do it again. This is useful for systems without libreboot.

+# We don't set this to fai check so we can't get into
