As we have seen with the OS 15 update, many people (including myself) have dead HA servers now. And I for one, have no way to get my hands on it for a couple of days (at the least).
There needs to be a way (if possible) for HA to recognize that its boot failed and it’s stuck at the GRUB menu to then switch to the previous Slot and reboot automatically.
This has happened before, and will happen again. Some type of auto-recovery script needs to be implemented. HA isn’t just for home automation anymore, its also for Home Security, and there is none when its dead.
Thank you for your time.
