I have both but just use pihole as a local DNS server/forwarder. I bump into too many random times where sites or redirects don’t work properly since they get blocked.

Consider using containers. I used to think this way, though now my goal is to get down to almost all containers since it’s nice to be able to spin up and down just what the one ‘thing’ needs.

If this is your fear, why not just have a will or something that specifically describes what to do and where to go?
