November 2024 monthly summary for srid/nixpkgs: Delivered a comprehensive OpenBSD packaging and tooling stack, expanding nixpkgs coverage and enabling OpenBSD workflows across Linux and FreeBSD platforms. Key features include packaging for OpenBSD boot tooling (boot-config, boot-ctags), bootloader and filesystem tooling (stand, makefs), and the OpenBSD kernel package (openbsd.sys); added a Linux compatibility layer to run OpenBSD build tools, and introduced aarch64-freebsd system configuration to build OpenBSD-related packages on this architecture. Extended openbsd.mkDerivation with extraNativeBuildInputs to support optional build-time dependencies. Bug fix: made OpenBSD make rules robust by removing hardcoded /bin/pwd references. Overall impact: accelerates downstream deployments, improves cross-OS packaging maintainability, and broadens platform coverage for OpenBSD in nixpkgs. Technologies/skills demonstrated: Nix packaging derivations, build configurations and patches, cross-architecture builds, and build tooling enhancements (compatibility layer and extra inputs).

OpenBSD portability, stability, and cross-repo alignment were the focus for 2024-10, with targeted improvements across raexera/nixpkgs and NixOS/nix. Key features delivered include OpenBSD dynamic linker support in nixpkgs (adding the OpenBSD rtld package and refining dynamic-linker handling to use the symlinked ld.so for non-static hosts) and consolidated OpenBSD compatibility enhancements in Nix (suppressing problematic linker flags, disabling GC, and adding utimensat support as a reliable alternative to lutimes). Major bugs fixed include libc build dependency cleanup in the OpenBSD setup hook to ensure cc-wrapper resolves dependencies correctly, preventing build failures. Overall impact: stronger OpenBSD support, improved build reliability, and greater cross-platform consistency, reducing maintenance churn and accelerating CI stability. Technologies/skills demonstrated include OpenBSD porting, Nix/Nixpkgs packaging, build-system tuning, dynamic linker configuration, cross-platform compatibility, and filesystem timestamp handling.
