That was my logic. I did rebuild my second one to Buster yesterday evening anyway, even though it was all working before. It didn't take long and it was nice to let the sync sort itself out and the lists to all get copied over automatically. I've changed the cron job to run gravity each night rather than just once a week so my blocklists were all synchronised when I got up this morning.gives you the flexibility of being able to add additional files located in LOCALSOURCEDIR2 and 3 to the sync.
