+# Refind does not set a layout=, it is compatible with the compat, uki

+#
+# systemd-boot could be made to work without the systemd flag, but this
+# makes no sense since in systemd(-utils) the boot flag already
+# requires the kernel-install flag.

+# Ukify hooks do nothing if the layout is not uki, so force this here.

+# Only one initramfs generator flag can be selected. Note that while
+# both dracut and ukify are UKI generators we don't block those because
