+// This unit-test reads all files enumerated in configs-test.txt file, loads
+// each of them and verify that they can be loaded.
+//
+// @todo: Unfortunately, we have this test disabled, because all loaded
+// configs use memfile, which attempts to create lease file in
+// /usr/local/var/bind10/kea-leases4.csv. We have couple options here:
+// a) disable persistence in example configs - a very bad thing to do
+//    as users will forget to reenable it and then will be surprised when their
+//    leases disappear
+// b) change configs to store lease file in /tmp. It's almost as bad as the
+//    previous one. Users will then be displeased when all their leases are
+//    wiped. (most systems wipe /tmp during boot)
+// c) read each config and rewrite it on the fly, so persistence is disabled.
+//    This is probably the way to go, but this is a work for a dedicated ticket.
+//
+// Hence I'm leaving the test in, but it is disabled.
