additional tables in database make upgrade fail
When upgrading the database is cleared/reloaded in install/update.php. If any additional tables (not included w/ ispconfig) are in the database the data reload fails and screws up the whole install. Obviously, the additional tables shouldn't be there in the first place but it'd be nice if everything didn't break because of them.
Easy fix: add the force switch -f to the mysql import commands. This will at least get the ispconfig data imported, leaving the user-added tables broken.
Better fix: only drop/re-import the tables that are "owned" by ispconfig
