for the credential fields that could not be determined atomically
at peer connection time, and which were later added by reading
augmenting credential data from

+ <filename>/proc/</filename>. Similarly, for credential objects
retrieved via <function>sd_bus_get_owner_creds()</function>, the
mask is set for the fields that could not be determined atomically
at bus creation time, but have been augmented. Similarly, for
<para><function>sd_bus_creds_get_augmented_mask()</function>
returns the mask of fields that have been augmented from data in

authorization decisions.</para>
