This function inspects the device named C<$partition> in isolation and
tries to determine what it is. It returns information such as whether
the partition is formatted, and with what, whether it is mountable,
and what it appears to contain (eg. a Windows root, or a Linux /usr).
-If C<use_windows_registry> is set to 1, then we will try to download
-and parse the content of the Windows registry (for Windows root
-devices). However since this is an expensive and error-prone
-operation, we don't do this by default. It also requires the external
-program C<reged>, patched to remove numerous crashing bugs in the
-upstream version.
+If the Perl module L<Win::Hivex(3)> is installed, then additional
+information is made available for Windows guests, if we can locate and
+read their registries.
The returned value is a hashref C<\%fs> which may contain the
