==================== 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 `__ and a EFI boot partition for maximum compatability.
