+====================
+Block Device EFI LVM
+====================
+
+This provides a block-device configuration for the ``vm`` element to
+get a disk suitable for EFI booting which uses LVM to define multiple
+volumes mounted to /, /tmp, /var, and /home.
+
+Please note that the sizes of the partitions may not
+be enough for production usage, they will need to be resized properly after
+deployment depending on the available disk size.
+
+Note on x86 this provides the extra `BIOS boot partition
+<https://en.wikipedia.org/wiki/BIOS_boot_partition>`__ and a EFI boot
+partition for maximum compatability.

+    Element block-device-efi-lvm has been added which is like block-device-efi
+    but defines an LVM logical group in the root partition. Four logical
+    volumes are defined in that group, mounted to /, /tmp, /var, and /home.
+
+    This volume layout will not meet all requirements, but this is more of an
+    example demonstrating the capability to encourage more usage of this
+    existing feature.
