Files which are installed as-is (any .service and other unit files, .conf files, .policy files, etc), are left as is. My assumption is that SPDX identifiers are not yet that well known, so it's better to retain the extended header to avoid any doubt. I also kept any copyright lines. We can probably remove them, but it'd nice to obtain explicit acks from all involved authors before doing that.

<para><function>sd_bus_message_set_destination()</function> sets the destination service name for the specified bus
|
||
message object. The specified name must be a valid unique or well-known service name.</para>
|
||
|
||
<para><function>sd_bus_message_set_sender()</function> sets the sender service name for the specified bus message
|
||
object. The specified name must be a valid unique or well-known service name. This function is useful only for
|
||
messages to send on direct connections as for connections to bus brokers the broker will fill in the destination
|
||
field anyway, and the sender field set by original sender is ignored.</para>
