+/**
+ * Enable the update.module by default on sites that upgrade.
+ *
+ * This cannot just rely on update.install to install the schema. If,
+ * in the future, someone decides to change the schema for the
+ * {cache_update} table, this update would cause uncertainty in the
+ * state of the DB, since the effect of running this update would
+ * change. For example, if the schema is changed in update #6101, and
+ * a site upgrades direct from 5.x to 6.1, update #6026 would create
+ * the table with the new schema, and then update #6101 would fail,
+ * since it's trying to alter the old schema into the new
+ * schema. Therefore, we must hard-code the particular version of the
+ * schema we mean during update #6026, and then future upgrades that
+ * might attempt to modify the schema of this table will be starting
+ * from a known state. See http://drupal.org/node/150220 for more.
