I had it briefly up and running and can only say... it's a bear, at least if you are trying to use it as a drop-in replacement with existing hardware. I'm sure I'll go back and sort it out at some point, but it left me just feeling tired and frustrated even when I had it doing most of what I wanted.

If you were thoughtful about hardware from the ground up, maybe it would be more straightforward, but I tried getting it running on just an old workstation with ubuntu installed on it that I use for very basic stuff like syncthing and it was just painful.

It would be nice to see better first-class add-on support. I found myself needing to SSH into a VM to get stuff into it, and even then it was twitchy in all the wrong ways. Would also be nice to see better support for the containerized version, because that's so much easier to distribute and execute compared to a VM. Next time I'll probably just try to do it all with docker and see if it hurts less, since I don't think any addons I was using were critical to begin with.

That said, if you're doing HA, get a dedicated piece of hardware for it. I suspect it vastly simplifies things.
