If the package you're using stays up to date and doesn't require much setup, you could plug a dockerTools.buildLayeredImage into the imageFile attribute. The name and the tag in the built image should match what's in the image attribute. An example (busybox is only included for debugging):

        image = "my-calibre-web:latest";
        imageFile = pkgs.dockerTools.buildLayeredImage {
          name = "my-calibre-web";
          tag = "latest";
          contents = [ pkgs.busybox ];
          config.Cmd = [
            "${pkgs.calibre-web}/bin/calibre-web"
            "-p"
            "/config/app.db"
            "-g"
            "/config/gdrive.db"
            "-i"
            "0.0.0.0"
          ];
        };

You don't have to wait for the enthusiasts to buy it up, these days the scalpers will take care of that for you. Not sure that that's going to help the 7800 price though.

That is indeed Don Quixote and I believe you'll find that he is tilting at that windmill

Having 3 or more identities often causes authentication to fail before it gets around to trying password authentication (or even all the possible keys). Recommend configuring the client to turn off PubkeyAuthentication by default (so that hosts that you don't have a key for will prompt for a password) and specify which key to use on the appropriate hosts using IdentityFile (might need to specifically turn PubkeyAuthentication back on, I don't remember how openssh handles having a default host block with specific host blocks)

You mean odometer, resetting the speedometer wouldn't be a bad thing.

Do you have any specific price/model recommendations?

The calibre content server also serves OPDS. Once you have a OPDS server in place you'll need to point a capable reader at it, but after that syncing and reading happens in the reader.

Typically xdg-ninja will tell you how to set things up so as many dot files and directories as possible end up in the correct xdg location instead of cluttering up the top level of your home directory.

self hosted alternatives for smart home and porn

How does self hosted porn even work and how am I the first person to notice that sitting there and mention it?

NetworkManager (network interface/connection management)

Pretty sure you mean systemd-networkd here. I find systemd-networkd to be very nice for headless systems, but NetworkManager seems to be a better fit for desktops because of the integrations it has available with KDE/Gnome/system tray

steamtinkerlaunch makes running Skyrim with ModOrganizer2 very simple. Other external programs will probably still be tricky though

Ubuntu has significant differences from Debian so it wouldn't make much sense to be able to install it as a "flavor" of Debian. However, *Ubuntu are pretty much already metapackages on top of regular Ubuntu. So instead of having different installers for each one, you could just make it an option during install and provide an easy means to add/switch other options later
