     * The symlink target path resolution requires reparsing, because it
     * can reference other symlinks. This is what happens, for example when
     * booting the installation from a removable hard-disk. We can have:
     *
     *          \SystemRoot ---> \Device\Harddisk1\Partition1\ReactOS
     * and:     \Device\Harddisk1\Partition1 ---> \Device\HarddiskVolume2

     * and we wish to resolve \SystemRoot to: \Device\HarddiskVolume2\ReactOS
     *
     * We then verify whether it prefixes the image file path obtained
     * from the step above, which is a fully reparsed path.
     *
     * - Using NtOpenSymbolicLinkObject(SYMBOLIC_LINK_QUERY) followed by
     *   NtQuerySymbolicLinkObject() would only resolve the first symlink
     *   but not the others (\Device\Harddisk1\Partition1 left as is).
     *
     * - Since \SystemRoot has to point to a directory, we try opening
     *   the directory itself: NtOpenFile(..., FILE_DIRECTORY_FILE).
     *
     * - A call to NtQueryInformationFile(FileNameInformation) alone on
     *   the obtained handle would only retrieve the FS directory name,
     *   i.e. \ReactOS , but not the whole NT path.
     *
     * - We therefore use NtQueryObject(), which allows retrieving the
     *   full resolved NT path (device name + FS directory name).
