This reduces the possibility of people losing their data during an upgrade.


If you portupgrade (or use any other system) to upgrade to a newer version
of Apache, data-dist will be overwritten with the new documentation that
comes with the new version of Apache.  data will not be touched.


As a result, if you left data as a symlink to data-dist, it still works
and shows you the most updated documentation.  However, if relink data
to a different directory, or replace the symlink with a real directory
with your site in it, the upgrade doesn't obliterate your data.
