GNU/Linux and possibly other GNU variants, with a focus on the
promotion and tight integration of GNU components–the GNU system.

This document lists milestones toward these goals.

The timeline below was written at the end of Dec. 2012. An updated and more
detailed list of the remaining milestones was posted at .

The actual timeline was of course slightly different than initially
envisioned, and so was the feature set–things like cross-compilation support
and the MIPS64 port were not planned back then. See the news section at and ‘NEWS’ for the release history.

* GNU Guix 0.1: Jan. 2013 (was: Dec. 2012)

** basic package management facilities

Including install, upgrade, remove, roll-back, and search.

** self-contained user-land distribution

- GNU/Linux-only, i686 and x86_64; optionally mipsel64
- ~100 non-X11 packages

** maybe integrated Nix code

* GNU Guix 0.2: Feb./Mar. 2013

** improved package management features

- user-environment hooks
- sophisticated handling of collisions when building a union (package
priorities, etc.)

** [[file:TODO::*add%20guix-pull][guix-pull tool]] to quickly update Guix and GNU for normal users
** support for fetching pre-built binaries

- this is known as the "binary-cache substituter" in Nix parlance

** auto-update facility available for GNU packages

** more packages

- Xorg
- Emacs

* GNU Guix 0.9: June 2013

** bootable GNU/Linux-Libre distro
** high-level OS configuration descriptive EDSL, à la NixOS

* GNU Guix 1.0: September 2013 (GNU anniversary release)

** bootable GNU/Linux-Libre distro with non-GUI installer
** usable for a range of hacker-style uses
Since its inception, the project has gone a long way towards that goal. Below
is a list of items we want for version "1.0" of the Guix System Distribution.
There will be a few 0.x releases by then to give the new features more
exposure and testing.

You're welcome to discuss this road map on or #guix on

* Features scheduled for 1.0

- larger & more robust build farm
+ we need a powerful, dedicated front-end
+ armhf-linux build machine
+ leave Hydra in favor of 'guix publish' + custom code?
- more OS features
+ LVM support
+ encrypted root
+ configurable name service switch
+ whole-system unit tests, using VMs
- more service definitions
+ mcron, postfix(?), wicd(?), etc.
- better 'guix system'
+ 'reconfigure' should be able to restart non-essential services
+ support for '--list-generations' and '--delete-generations'
- better 'guix pull'
+ using Git to fetch the source instead of re-downloading everything
+ build more quickly
+ install new .mo files and new manual
+ authentication of the Guix source: use signed commits?
- simplified, purely declarative service list in 'operating-system'
+ it should be possible to inspect the service instance declarations and
- GUIs
+ integrate guix-web?
+ guile-ncurses installer?
- 'guix publish'?

* Features for later

- complete GNU/Hurd port
- use content-based addressing when downloading substitutes to reduce
bandwidth requirements
+ design nar v2 format where file contents are replaced by their hashes
+ leverage /gnu/store/.links
- binary origin tracking
+ keep signatures in sqlite.db
+ preserve signatures upon import/export
- peer-to-peer distribution of updates (GNUnet?)
- more deterministic builds
+ identify & fix sources of non-determinism in builds
+ strengthen guix-daemon containers to further increase reproducibility
+ trusting-trust: bootstrap with different tool chains
+ fixed-point: re-bootstrap until fixed point is reached
+ distributed validation: compare contents of store items with others
* resist a compromise
- reproducible containers: mix of 'guix environment' and 'guix system vm'
- execute code with least privilege
+ build containers like guix-daemon does
+ provide a Plash-like interface in Bash
- daemon rewritten in Guile
- more dmd integration
+ monitor network interfaces and start/stop events based on that
+ include a DHCP client written in Scheme
