  1. a gentle intro to functional package management with GNU Guix

  2. Package managers are really useful. But they can be so frustrating!

  3. Package managers are really useful. But they can be so frustrating!

  4. Version conflicts Old software Suspenseful upgrades The only way is forward Changes affect all users Trust?

  5. No package management You are on your own. External repos EPEL, PPAs, AUR... more con fl icts , more to trust Application-specific packaging gem , cabal , pip , cpan , npm : more packages, less management Build your own system package Relocatable rpm , deb , PKGBUILD, ... Meta package managers Generate system packages with e.g. fpm Giving up Packaging is hard, let’s take snapshots .

  6. Functional packaging headers sources build tools libraries ... cabba9e- emacs -24.5/ bin emacs lib ...

  7. Functional packaging cabba9e- emacs -24.5/ Same inputs? bin emacs Same output! lib ... dedbeef- emacs -24.5/ Different inputs? bin emacs Different outputs. lib ...

  8. GNU Guix Guix client Build daemon RPCs (guix packages) (guix store) Isolated build processes chroot with declared inputs Store
