+Using this, you can boot into fai with pxe-kexec without changing the
+dhcp server. Note, if you are booting using fai-cd, the pxe config does
+nothing, and only flags affecting FAI_ACTION will have any affect. You
+can change the fai flags in the grub config, for example in
+./grub.cfg.autodiscover, or at runtime by editing a grub menu option.
+We could probably also set FAI_FLAGS the same way we set FAI_ACTION,
+but I haven't tried it.
