Describe the issue you are experiencing I see GNU GRUB with 4 options - Slot A, Slot B, Slot A rescue shell, Slot B rescue shell. Selecting any of them results in a message that it's unable to boot...
Adjacent question: is there a compelling reason to run HAOS? I run my HA setup in docker on a Proxmox CT, using Portainer/Watchtower to manage, so genuinely wondering if there would be benefits I'm missing out on.
The add-on store that’s managed and updated via the supervisor. It does the same thing as your setup, but integrates into HA nicer (automatic connectivity to HA for the containers, when they need it). If you’re happy with how your setup works then there’s no compelling reason to switch.
Interesting about the backups bit. The functionality's there in the UI to create backups, so kinda weird you can't restore them. Like most docker containers, my HA config sits on a bind mount, and I just back that up nightly.
When you say add-ons, are there specific ones I'm missing out on? I have HACS, and frequently install all manner of integrations and front-end Lovelace add-ons.
"Add-ons" is a separate category of thing, and more substantial than integrations/Lovelace stuff. If you haven't noticed any missing you're probably fine. But some popular ones are DuckDNS and Mosquitto Broker.
Ah, got it. Thanks - this makes a lot of sense now. Looks like it's so the HAOS Supervisor container can manage all the things that, in theory, I already handle myself with external tools.
