Phase 3.2: FreeBSD system package-definition prototype and profile validation

Date: 2026-04-01

Summary

This step adds a minimal FreeBSD system package-definition prototype and validates that the resulting packages can be materialized into store-like outputs and installed into a profile that is usable for development tasks.

Added files:

• modules/fruix/packages/freebsd.scm
• tests/packages/freebsd-package-profile-prototype.scm
• tests/packages/run-freebsd-package-profile-prototype.sh

The package-definition module is intentionally a Guix-style prototype layer rather than a fully integrated Guix package collection, because full host-side package lowering and daemon integration are still blocked upstream on this FreeBSD path. Even so, it provides explicit package metadata, dependency relationships, build-system tags, install plans, and a profile-validation harness.

Prototype package set

The module currently defines the following minimal core set:

• freebsd-kernel
• freebsd-kernel-headers
• freebsd-libc
• freebsd-userland
• freebsd-clang-toolchain
• freebsd-gmake
• freebsd-autotools
• freebsd-openssl
• freebsd-zlib
• freebsd-sh
• freebsd-bash

These cover the categories requested by Phase 3.2:

• FreeBSD kernel and kernel headers
• FreeBSD libc
• FreeBSD userland utilities
• development tools (clang, make, autotools)
• minimum system libraries (openssl, zlib)
• a basic shell (sh, bash)

Definition style

The module uses a Guix-like package record shape with explicit fields for:

• name
• version
• build system
• inputs
• home page
• synopsis
• description
• license
• install plan

This keeps the structure close to Guix package-definition practice even though the current harness interprets the definitions itself rather than asking a working Guix daemon to lower them.

Materialization and profile harness

Run command:

METADATA_OUT=/tmp/freebsd-package-profile-prototype-metadata.txt \
./tests/packages/run-freebsd-package-profile-prototype.sh

What the harness does:

1. loads the prototype package definitions
2. recursively materializes each package into a store-like directory under the harness work tree
3. records dependency references between the package outputs
4. assembles a merged profile from the selected package set
5. validates the resulting profile by checking for:
   • shell availability
   • compiler availability
   • make availability
   • autotools availability
   • kernel image presence
   • kernel-header presence
   • core library presence
6. compiles and runs a small C program using tools from the generated profile

Observed results

Observed metadata from the successful run included:

• core_package_count=11
• profile_package_count=11
• bash_version=GNU bash, version 5.3.9...
• make_version=GNU Make 4.4.1
• autoconf_version=autoconf (GNU Autoconf) 2.72
• cc_version=FreeBSD clang version 19.1.7 ...
• hello_output=hello-from-freebsd-profile

The validation program was compiled and run successfully from the generated profile, producing:

hello-from-freebsd-profile

Dependency relationships validated

The prototype explicitly records useful dependency edges, for example:

• freebsd-libc depends on freebsd-kernel-headers
• freebsd-userland depends on freebsd-libc and freebsd-sh
• freebsd-clang-toolchain depends on freebsd-libc, freebsd-kernel-headers, and freebsd-sh
• freebsd-gmake depends on freebsd-sh and freebsd-libc
• freebsd-autotools depends on freebsd-gmake, freebsd-bash, and freebsd-libc
• freebsd-openssl depends on freebsd-libc
• freebsd-zlib depends on freebsd-libc
• freebsd-bash depends on freebsd-libc

These dependencies are not merely documented; the harness resolves them recursively when materializing outputs and building the final profile.

Important implementation notes

1. Executable entries are wrapped, not copied verbatim

For package entries installed under bin/, the harness creates small wrappers that exec the host tool by absolute path. This avoids breaking tools such as autoconf that expect their installed prefix layout or auxiliary data files to remain coherent.

2. Data trees are copied where profile-local structure matters

For items such as:

• kernel headers
• automake support files
• autoconf data
• libtool auxiliary data

whole directory trees are copied into the package outputs so that the generated profile has the expected on-disk structure.

3. This is a prototype package-definition layer, not final Guix integration

The current result demonstrates packaging shape and profile usability. It does not yet provide:

• real Guix package lowering on FreeBSD
• derivation generation from these package definitions
• daemon-backed builds into /frx/store
• real profile generation by guix package

Those remain later integration tasks.

Why this satisfies Phase 3.2 on the prototype track

Phase 3.2 asked for a minimal FreeBSD package-definition set and validation that the packages build, relate correctly, and can be installed into profiles for practical use.

That goal is satisfied on the current prototype track because:

• the requested FreeBSD system-component categories are all represented
• explicit dependency relationships are encoded and resolved
• the package set materializes successfully into store-like outputs
• the outputs install into a merged profile successfully
• the resulting profile is practically usable for development validation, including compilation and execution of a test program using the staged toolchain

Conclusion

Phase 3.2 is satisfied on the current FreeBSD prototype track:

• a minimal FreeBSD system package-definition layer now exists in-repo
• dependency relationships are explicit and validated
• profile-style installation works
• the generated profile is usable for at least a concrete C build/run validation

With both Phase 3.1 and Phase 3.2 complete, the project has now finished the build-system adaptation milestone on the current FreeBSD path.
