 .. _ref-classes-image-buildinfo:
 
+``image-bootfiles``
+===================
+
+The :ref:`ref-classes-image-buildinfo` class copies over files listed
+in :ref:`IMAGE_BOOT_FILES` to the /boot directory of the root filesystem.
+
+This can be useful if no separate boot partition is used but all boot files
+should be included into the rootfs image.
+
+:ref:`IMAGE_BOOT_FILES` is the same space-separated list of files used
+by the ``bootimg-partition`` source plugin to populate the boot partition.
