rsync - Sep 2003 - Option --link-dest creates unexplained subdirectory

The following backup script works fine for test cases but for
 doing a backup of 750 MB, the directory daily.1 has
 a subdirectory daily.0, that is, there is
 daily.1/daily.0
 daily.2/daily.1
 daily.3/daily.2
 The directory daily.0 has nothing strange, no unusual links
 at the top level neither hard or soft.
 Also, the original directory has not unusual links.
 All directories are in the same computer.
 Running on a dual-processor Xeon, Linux Red Hat 7.3, kernel 2.4.21
 The version is
 $ /usr/local/Backup/bin/rsync --version
 rsync  version 2.5.6  protocol version 26

It isn't rsync creating those.

Somehow your rotation is doing it.  Look at the names.
${interval}.${iter_value}/${interval}.${oneless}
