I run #pi-hole on my #umbrel host and configure it as the DNS server for my network, but every time I update Umbrel apps, things don't restart properly,including pi-hole.
I have a feeling there's some race condition that apps are needing DNS to update/restart an pi-hole is not up yet, perhaps pi-hole itself (or rather the docker container) needs DNS to update too.
So right now I have to remove the DNS server configuration everytime I do updates.
I suppose I just need to specify a secondary DNS that will be used as a backup
