The bsd-user-4-linux project ports BSD user-mode emulation for QEMU to Linux. The primary goal is to enable unmodified FreeBSD binaries to run on modern Linux systems. Additionally, the project aims to provide multi-platform container images with a functional FreeBSD environment and ready-to-use GitHub Actions templates.

Current Status:

  • The initial port successfully runs make -jN buildworld.

  • Most command-line tools are working as expected (sh, bash, find, grep, git, clang, etc).

  • A GitHub Actions pipeline builds x86_64 emulation images for:

    • linux/386

    • linux/amd64

    • linux/arm/v5

    • linux/arm64/v8

Next Steps: * Implement container integration.

How You Can Help:

  • Test with your preferred toolchain, report issues, or contribute fixes.

  • Build and test non-x86_64 emulation images (e.g., FreeBSD/arm64 on Linux/x86_64). The code works on BSD but needs testing on Linux.

  • Support us on Patreon.
