In both styles, same key words are automatically merged when parsing it

at boot time. So you can append similar trees or key-values.

Same-key Values

---------------

It is prohibited that two or more values or arrays share a same-key.

For example,::

 foo = bar, baz

 foo = qux  # !ERROR! we can not re-define same key

If you want to append the value to existing key as an array member,

you can use ``+=`` operator. For example::

 foo = bar, baz

 foo += qux

In this case, the key ``foo`` has ``bar``, ``baz`` and ``qux``.

However, a sub-key and a value can not co-exist under a parent key.

For example, following config is NOT allowed.::

 foo = value1

 foo.bar = value2 # !ERROR! subkey "bar" and value "value1" can NOT co-exist

==============================

Since the boot configuration file is loaded with initrd, it will be added

to the end of the initrd (initramfs) image file. The Linux kernel decodes

the last part of the initrd image in memory to get the boot configuration

data.

to the end of the initrd (initramfs) image file with size, checksum and

12-byte magic word as below.

[initrd][bootconfig][size(u32)][checksum(u32)][#BOOTCONFIG\n]

The Linux kernel decodes the last part of the initrd image in memory to

get the boot configuration data.

Because of this "piggyback" method, there is no need to change or

update the boot loader and the kernel image itself.
