This document lists milestones toward these goals.

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.

The actual timeline was of course slightly different than initially
|
* Features scheduled for 1.0

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
|
|
||||||
http://www.gnu.org/software/guix/ and ‘NEWS’ for the release history.
|
|
||||||
|
|
||||||
* GNU Guix 0.1: Jan. 2013 (was: Dec. 2012)
|
- 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
|
||||||
|
settings
|
||||||
|
- GUIs
|
||||||
|
+ integrate guix-web?
|
||||||
|
+ guile-ncurses installer?
|
||||||
|
- 'guix publish'?
|
||||||
|
|
||||||
** basic package management facilities
|
* Features for later
|
||||||
|
|
||||||
Including install, upgrade, remove, roll-back, and search.
|
- complete GNU/Hurd port
|
||||||
|
- use content-based addressing when downloading substitutes to reduce
|
||||||
** self-contained user-land distribution
|
bandwidth requirements
|
||||||
|
+ design nar v2 format where file contents are replaced by their hashes
|
||||||
- GNU/Linux-only, i686 and x86_64; optionally mipsel64
|
+ leverage /gnu/store/.links
|
||||||
- ~100 non-X11 packages
|
- binary origin tracking
|
||||||
|
+ keep signatures in sqlite.db
|
||||||
** maybe integrated Nix code
|
+ preserve signatures upon import/export
|
||||||
|
- peer-to-peer distribution of updates (GNUnet?)
|
||||||
* GNU Guix 0.2: Feb./Mar. 2013
|
- more deterministic builds
|
||||||
|
+ identify & fix sources of non-determinism in builds
|
||||||
** improved package management features
|
+ strengthen guix-daemon containers to further increase reproducibility
|
||||||
|
+ trusting-trust: bootstrap with different tool chains
|
||||||
- user-environment hooks
|
+ fixed-point: re-bootstrap until fixed point is reached
|
||||||
- sophisticated handling of collisions when building a union (package
|
+ distributed validation: compare contents of store items with others
|
||||||
priorities, etc.)
|
* resist a hydra.gnu.org compromise
|
||||||
|
- reproducible containers: mix of 'guix environment' and 'guix system vm'
|
||||||
** [[file:TODO::*add%20guix-pull][guix-pull tool]] to quickly update Guix and GNU for normal users
|
- execute code with least privilege
|
||||||
** support for fetching pre-built binaries
|
+ build containers like guix-daemon does
|
||||||
|
+ provide a Plash-like interface in Bash
|
||||||
- this is known as the "binary-cache substituter" in Nix parlance
|
- daemon rewritten in Guile
|
||||||
|
- more dmd integration
|
||||||
** auto-update facility available for GNU packages
|
+ monitor network interfaces and start/stop events based on that
|
||||||
|
+ include a DHCP client written in Scheme
|
||||||
** more packages

|
||||||
|
|
||||||

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