-                <para><function>sd_id128_randomize()</function>
-                generates a new randomized 128 bit ID and returns it
-                in <parameter>ret</parameter>. Every invocation
-                returns a new randomly generated ID. This uses the
-                <filename>/dev/urandom</filename> kernel random number
-                generator.</para>
-
-                <para><function>sd_id128_get_machine()</function>
-                returns the machine ID of the executing host. This
-                reads and parses the
-                <citerefentry><refentrytitle>machine-id</refentrytitle><manvolnum>5</manvolnum></citerefentry>
-                file. This function caches the machine ID internally
-                to make retrieving the machine ID a cheap
-                operation.</para>
-
-                <para><function>sd_id128_get_boot()</function> returns
-                the boot ID of the executing kernel. This reads and
-                parses the
-                <filename>/proc/sys/kernel/random/boot_id</filename>
-                file exposed by the kernel. It is randomly generated
-                early at boot and is unique for every running kernel
-                instance. See
-                <citerefentry><refentrytitle>random</refentrytitle><manvolnum>4</manvolnum></citerefentry>
-                for more information. This function also internally
-                caches the returned ID to make this call a cheap
-                operation.</para>

-                a UUID v4 compatible
-                ID. <function>sd_id128_get_machine()</function> will
-                also return a UUID v4 compatible ID on new
-                installations, but might not on older. It is possible
-                to convert the machine ID into an UUID v4 compatible
-                one. For more information see
