I've been wanting to do this since at least 2017, when I started to work on a [homestead project](https://git.alanpearce.eu/homestead/tree/src?h=2017), which I didn't quite finish. + +The recent release of [Bun](https://bun.sh/), which touts itself as an "all-in-one JavaScript toolkit" encouraged me to play around with it. I have to say, I am surprised by how energising it was; an antidote to the "JavaScript fatigue" I've read about and definitely experienced. + +I decided that I'd start by serving my site using Bun's web server, then I added site generation later. I have been intrigued by the idea of DOM templating ever since I read about it on [Camen Design](https://camendesign.com/dom_templating) [in 2012](https://camendesign.com/code/dom_templating/domtemplate_v4.rem) and I've enjoyed putting it into practice. diff --git a/content/post/nixos-on-nanopi-r5s.md b/content/post/nixos-on-nanopi-r5s.md new file mode 100644 index 0000000..185bd30 --- /dev/null +++ b/content/post/nixos-on-nanopi-r5s.md @@ -0,0 +1,142 @@ ++++ +title = "Running NixOS on a NanoPi R5S" +date = 2023-07-30T08:51:46Z +[taxonomies] +tags = ["nixos", "home-networking", "infrastructure"] ++++ + +I managed to get [NixOS](https://nixos.org) running on my [NanoPi R5S](https://www.friendlyelec.com/index.php?route=product/product&product_id=287) ([FriendlyElec Wiki](https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R5S)). + +Firstly, I flashed a pre-built stock Debian image from [inindev](https://github.com/inindev/nanopi-r5) to an SD card.

I only really needed to this to ensure UBoot was correctly installed; I think there will be an easier way to do it. + +I had nix already installed on the <abbr title="Non-Volatile Memory Express">NVMe</abbr> <abbr title="Solid-State Drive">SSD</abbr> along with a home directory.
