From my experience with tailscale so far - there are so many different ways to have it configured well. If it works well for you having it on the host, then go for it. I have home assistant in a VM with tailscale and tailscale on the (windows) host. This works well for my needs and I don’t mind having it running “twice”

Can I request a hack? How do I handle several different versions of Python installed, which one is used for pip stuff, and how sudo/running as services changes all of this.

I chose to set up grafana, mqtt, etc for an RV instead of home assistant. Little more lightweight for the raspberry pi 3 I used. Pulling together solar info, so we could see how long the AC would keep running on the road

There’s university programs and even guys in their garages who do a lot of the processes in small batches on very old nodes. For example, a material science program may be trying to find new transistor materials, where the nodes don’t matter much. ASML is not the only tooling manufacturer, but they are very good at it. EUV sources are very complicated, so that is a large barrier to overcome. Many smaller outfits like Qorvo run fabs in North America that you may not know about. Clean rooms are a requirement, but that’s not a significant barrier at the very small scale (an entire university may only have one, most experiments done outside of it). Nothing is done by a single machine, it takes an entire building of machines (and supporting facilities)

Are the entire blueprints for Airbus’s manufacturing facilities open to the public?

If you are interested in broad concepts that are surprisingly similar processes in a factory, I might suggest watching printed circuit board factory tours. Lithography is lithography.

I think I had a similar problem a couple weeks ago. Make sure they are adding the device to your tailnet, by default it adds the new machine to their own tailnet. I know I hit some kind of issue like that, at least.
