    <para>In addition to the error names user programs define, D-Bus
    knows a number of generic, standardized error names that are
    listed below.</para>

    <para>In addition to this list, in sd-bus, the special error
    namespace <literal>System.Error.</literal> is used to map
    arbitrary Linux system errors (as defined by <citerefentry
