From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I currently use NixOS and nix-darwin, and I've enjoyed the ride so far. I use flakes with direnv for reproducible development environments, and this has been working out well. I've also been impressed with using Nix to build OCI containers.
The learning curve isn't flat, but the ecosystem is fantastic.
Makes sense; one of the big things about it that interests me is the dockerfile generation. Although, I should probably get a better understanding of dockerfiles themselves before jumping into that; I have a habit of forgetting the order of carts and horses
Dockerfiles act as instructions for thedocker(or compatible) CLI to use for building OCI container images. Images may or may not have layers and can be exported as a tarball for inspection (with tools likedive).Nix provides native support for building container images, and the resulting archive must be loaded using
docker load. There is another library (nix2container) that aims for better performance and relies onskopeofor copying the built image to a docker-compatible server, local or remote.Just wanted to share a some of the information I've learned. Cheers!
