Home Assistant has a lot of moving parts, all the add-ons and extra user stuff. So they provide a docker image with everything you need, they also provide a full appliance install for easy setup.
If you did all that as a package install, you would complain about all the dependancies and if you didnt install the right version of something Home Assistant might not work at all
You're hand-waving the answer to my question :-) What add-ons and extra user stuff require Home Assistant to be an OS?
If you did all that as a package install, you would complain about all the dependancies and if you didnt install the right version of something Home Assistant might not work at all
That's not how packages work. The packagers take care of all that. That's the point.
