* via @invocation.
*

* check which could be a very long time since it may involve

* it. If <quote>auth.no_user_interaction</quote> in @options is %TRUE

* expected to take a long time.
*
* See <xref linkend="udisks-polkit-details"/> for the variables that

* in all checks. For example, any check involving a #UDisksDrive or a

* the block device file e.g. <quote>/dev/vg_lucifer/lv_root</quote>

* that isn't on a drive or block device, for example calls on the
* <link linkend="gdbus-interface-org-freedesktop-UDisks2-Manager.top_of_page">Manager</link>
* object.
