I think the point with all of these is that they are “cloud”-based. Except instead of the cloud being someone else’s computer, it’s your own. Let’s take Immich, for example. Sure I could keep all my photos on my phone. But what if I lose or break my phone? What if I have an actual camera with an SD card and I want to offload those photos? Self-hosting lets me keep a backup. I can set up a server with redundant drives that itself backs up to a server in another location with its own separate drives. Thus, I have my own safe cloud storage.

Definitely hide so that they can’t complete their quest of meeting all the people.

I don’t think that’s possible if they don’t have a working boot drive.

Oh I see now. You should be able to import them. Worst case is you can’t then you’re back where you are now. There shouldn’t be any data loss.

Yeah. As far as I understand it, exporting is more of a config thing. You can shut down your system asd boot it while missing drives (done this by accident) and boot while missing, and it’ll say there’s an issue with it. Shut down, pop the drives back in and you’re good to go on boot.

You can just drop in a new boot drive and install from a usb. I do recommend setting up a boot pool mirror though. This way if one goes down, you have a spare that can be used to help recover more quickly.

This is a legit method for building small things like that where you can use the brick-like shape of the bag when it’s hardened. You just need to make sure the concrete gets soaked all the way through with a hose or rain.
