REPRO.CONF(5)

📦 in arch rolling

💖 REPRO.CONF(5) — the repro config file, bestie edition 💖

okay so this is the manual page for repro.conf, section 5 of the manual. grab a lil snack, we're gonna go through it together 🍓

✨ NAME ✨

repro.conf — the configuration file for repro. that's it, that's the vibe 💅

🦋 SYNOPSIS 🦋

/etc/archlinux-repro/repro.conf,
$XDG_CONFIG_HOME/archlinux-repro/repro.conf, ~/.repro.conf

three whole places this file can live, and you only need one of them 😌

🌸 DESCRIPTION 🌸

so the config options for repro live in repro.conf, and here's the thing — this file gets sourced by repro on launch. which means it's not just parsed, it's executed like a script, iykyk 🙈

and every single variable in there, whether it's described below or not, gets exported to the build environment. all of them. no gatekeeping ✨

the system-wide configuration file is at:

/etc/archlinux-repro/repro.conf

and you can override individual options per-user in:

$XDG_CONFIG_HOME/devtools-repro/repro.conf

or in:

~/.repro.conf

and the first one takes priority over the second one. so $XDG_CONFIG_HOME/devtools-repro/repro.conf wins the crown 👑

🎀 OPTIONS 🎀

here's the whole roster, no skips, no skimming, we're doing all of them 🫶

  • BOOTSTRAPMIRROR="https://mirror.archlinux.no/iso/latest" — this is where the bootstrap image gets downloaded from, the one used for creating the container. default points at https://mirror.archlinux.no/iso/latest 💖
  • BUILDDIRECTORY="/var/lib/repro" — where the containers should be stored. default is /var/lib/repro 🎀
  • DIFFOSCOPE="diffoscope" — sets the diffoscope(1) command that gets run whenever unreproducible packages show up. default is just diffoscope 🔍
  • HOSTMIRROR="http://mirror.neuf.no/archlinux/\$repo/os/\$arch" — the mirror that pacman uses inside the container. default is http://mirror.neuf.no/archlinux/\$repo/os/\$arch — and yes, those \$repo and \$arch escapes are doing exactly what you think they're doing, leave them alone 😭
  • IMGDIRECTORY="/tmp/arch_img" — where the Arch Linux bootstrap image gets downloaded to. default is /tmp/arch_img 🦋
  • MAKEFLAGS="-j$(nproc)" — configures MAKEFLAGS on the node. default is -j$(nproc), and it's set that way for optimization purposes. ngl, it's giving efficiency ✨
  • ARCH_ARCHIVE_CACHE="https://archive.archlinux.org/packages" — configures the archive mirror used when downloading archived packages. default is https://archive.archlinux.org/packages 📦
  • NOCHECK=0 — decides whether makepkg gets run with or without --nocheck inside the container. default is 0.
⚠️ heads up bestie: this could affect the build process. like, actually. don't just flip it for funsies 💀
  • CACHEDIR=cache — picks the cache directory location. the default, cache, creates a cache in the working directory 🍓
  • OUTDIR=./build — picks the build output directory. the default, ./build, creates ./build in the working directory 👑

  • repro(8) — go read that one next, it's the main character 💜
