-If you're reading this, it's most likely because you had replaced /var/lib/mysql
-with a symlink, then upgraded to a new version of mysql, and then dpkg
-removed your symlink (see #182747 and others). The mysql packages noticed
-that this happened, and as a workaround have restored it. However, because
-/var/lib/mysql seems to have been re-created in the meantime, and because
-we don't want to rm -rf something we don't know as much about, we are going
-to leave this unexpected directory here. If your database looks normal,
-and this is not a symlink to your database, you should be able to blow
-this all away.
