> +    Create MBR + EFI boot partition
> +
> +    This plugin creates a boot partition that contains both
> +    legacy BIOS and EFI content. It will be able to boot from both.
> +    This is useful when managing PC fleet with some older machines
> +    without EFI support.
> +
> +    Note it is possible to create an image that can boot from both
> +    legacy BIOS and EFI by defining two partitions : one with arg
> +    --source bootimg-efi  and another one with --source
> bootimg-pcbios.
> +    However, this method has the obvious downside that it requires
> TWO
> +    partitions to be created on the storage device.
> +    Both partitions will also be marked as "bootable" which does not
> work on
> +    most BIOS, has BIOS often uses the "bootable" flag to determine
> +    what to boot. If you have such a BIOS, you need to manually
> remove the
> +    "bootable" flag from the EFI partition for the drive to be
> bootable.
> +    Having two partitions also seems to confuse wic : the content of
> +    the first partition will be duplicated into the second, even
> though it
> +    will not be used at all.
> +
> +    Also, unlike "isoimage-isohybrid" that also does BIOS and EFI,
> this plugin
> +    allows you to have more than only a single rootfs partitions and
> does
> +    not turn the rootfs into an initramfs RAM image.
> +
> +    This plugin is made to put everything into a single /boot
> partition so it
> +    does not have the limitations listed above.
> +
> +    The plugin is made so it does tries not to reimplement what's
> already
> +    been done in other plugins; as such it imports "bootimg-pcbios"
> +    and "bootimg-efi".
> +    Plugin "bootimg-pcbios" is used to generate legacy BIOS boot.
> +    Plugin "bootimg-efi" is used to generate the UEFI boot. Note
> that it
> +    requires a --sourceparams argument to know which loader to use;
> refer
> +    to "bootimg-efi" code/documentation for the list of loader.
> +
> +    Imports are handled with "SourceFileLoader" from importlib as it
> is
> +    otherwise very difficult to import module that has hyphen "-" in
> their
> +    filename.
> +    The SourcePlugin() methods used in the plugins (do_install_disk,
> +    do_configure_partition, do_prepare_partition) are then called on
> both,
> +    beginning by "bootimg-efi".
> +
> +    Plugin options, such as "--sourceparams" can still be passed to a
> +    plugin, as long they does not cause issue in the other plugin.
> +
> +    Example wic configuration:
> +    part /boot --source bootimg-biosplusefi
> --sourceparams="loader=grub-efi"\\

+    Create MBR + EFI boot partition
+
+    This plugin creates a boot partition that contains both
+    legacy BIOS and EFI content. It will be able to boot from both.
+    This is useful when managing PC fleet with some older machines
+    without EFI support.
+
+    Note it is possible to create an image that can boot from both
+    legacy BIOS and EFI by defining two partitions : one with arg
+    --source bootimg-efi  and another one with --source bootimg-pcbios.
+    However, this method has the obvious downside that it requires TWO
+    partitions to be created on the storage device.
+    Both partitions will also be marked as "bootable" which does not work on
+    most BIOS, has BIOS often uses the "bootable" flag to determine
+    what to boot. If you have such a BIOS, you need to manually remove the
+    "bootable" flag from the EFI partition for the drive to be bootable.
+    Having two partitions also seems to confuse wic : the content of
+    the first partition will be duplicated into the second, even though it
+    will not be used at all.
+
+    Also, unlike "isoimage-isohybrid" that also does BIOS and EFI, this plugin
+    allows you to have more than only a single rootfs partitions and does
+    not turn the rootfs into an initramfs RAM image.
+
+    This plugin is made to put everything into a single /boot partition so it
+    does not have the limitations listed above.
+
+    The plugin is made so it does tries not to reimplement what's already
+    been done in other plugins; as such it imports "bootimg-pcbios"
+    and "bootimg-efi".
+    Plugin "bootimg-pcbios" is used to generate legacy BIOS boot.
+    Plugin "bootimg-efi" is used to generate the UEFI boot. Note that it
+    requires a --sourceparams argument to know which loader to use; refer
+    to "bootimg-efi" code/documentation for the list of loader.
+
+    Imports are handled with "SourceFileLoader" from importlib as it is
+    otherwise very difficult to import module that has hyphen "-" in their
+    filename.
+    The SourcePlugin() methods used in the plugins (do_install_disk,
+    do_configure_partition, do_prepare_partition) are then called on both,
+    beginning by "bootimg-efi".
+
+    Plugin options, such as "--sourceparams" can still be passed to a
+    plugin, as long they does not cause issue in the other plugin.
+
+    Example wic configuration:
+    part /boot --source bootimg-biosplusefi --sourceparams="loader=grub-efi"\\
+               --ondisk sda --label os_boot --active --align 1024 --use-uuid
