> If I have some developers using an ARM based macbook, and some devs on an x86_64 based machine, is it easy to support both without much maintenance? Yes. I maintain a small collection of Nix packages at my job (some of which come straight from upstream, some of which I've written in-house and are out-of-tree) for use in development and CI environments. We currently support both Intel and Apple Silicon Macs as well as x86_64 Linux environments. There are a couple of small OS-specific tweaks in one or two packages (which we inherit from those packages, which ship OS-specific scripts). There is no architecture-specific code in the repo; I literally never have to think about it. Target platforms are all tested in CI. Deployment targets (users, CI runners) on all supported platforms get the exact same versions of everything, in binary form appropriate to their architecture.
