Projektgeschichte

The GitHub repository was created in March 2024, and the official README presents the project as a from-scratch Rust implementation inspired by Debian's strip-nondeterminism. The README explains the Fedora/RHEL motivation directly: the author wanted tooling suitable for RPM buildroots without pulling Perl into all build environments, and with behavior tuned for Fedora-style artifacts such as Python bytecode.

The project quickly grew beyond a single timestamp scrubber. add-det rewrites supported archive and generated-file formats in place while preserving safety on failures; linkdupes handles duplicate files in build trees while accounting for SOURCE_DATE_EPOCH and SELinux contexts.

Adoptionsgeschichte

The README documents intended integration with RPM build-root postprocessing through --brp mode and links to redhat-rpm-config pull requests adding add-det and linkdupes to %__os_install_post. The supplied package-manager metadata also shows packaging in Homebrew, Fedora/DNF, Nix, and Arch/pacman.

Wie es verwendet wird

Package maintainers run add-det over files or directories to clamp or strip metadata in ar, jar, javadoc HTML, gzip, pyc, and zip outputs. In check mode it reports files that would be modified without rewriting them, which makes it useful in reproducibility tests.

linkdupes walks build output trees and hardlinks files with identical content and compatible metadata. Its package-build angle is that it can clamp mtimes against SOURCE_DATE_EPOCH and avoid unsafe hardlinking across mismatched SELinux contexts.

Warum Paket-Nerds sich dafür interessieren

This is a small but very package-manager-native tool: it encodes distro build-root concerns, reproducible-build conventions, and RPM macro integration in one binary crate. For package nerds, the interesting part is not a new file format but a practical attempt to make post-build cleanup deterministic, portable across builders, and cheap to add to packaging pipelines.
