"du -a" will count each link (directory entry) once, even if it refers
to an inode that was already counted, thus for every file that has two
links, your "du -a|wc -l" will be off by one (and off by two for each
3-link file, etc.).

In the news spool directory, multiple links are used when articles are
crossposted.
