+# Options for the dracut-uefi kernel hook script installed by the dracut package.

+# To enable EFI bundle creation in dracut, uncomment
+#CREATE_UEFI_BUNDLES=yes
+# This requires an EFI stub, provided by the gummiboot package,
+# as well as setting the kernel command line.
+# Booting without a kernel command line is unsupported.
+
+# You can set the kernel command line with

+# or by setting kernel_cmdline in a dracut.conf(5) file.
+# The bundle can also use the command line from a bootloader / boot manager
