#+TITLE: Tentative GNU Guix Road Map

The goals of the GNU Guix project are two-fold:

  - to build a purely functional package manager, based on Nix and
    Guile;

  - to use it to build a practical 100% free software distribution of
    GNU/Linux and possibly other GNU variants, with a focus on the
    promotion and tight integration of GNU components–the GNU system.

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 guix-devel@gnu.org or #guix on
the Libera Chat IRC network!

* 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
      settings
  - 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 hydra.gnu.org 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 shepherd integration
    + monitor network interfaces and start/stop events based on that
    + include a DHCP client written in Scheme
bdff2663b'>services: dbus: Deprecate 'polkit-service' procedure....* doc/guix.texi (Desktop Services): Replace 'polkit-service' with 'polkit-service-type'. * gnu/services/dbus.scm (polkit-service): Deprecate procedure. * gnu/tests/docker.scm (%docker-os): Use polkit-service-type. * gnu/tests/virtualization.scm (%libvirt-os): Ditto. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Bruno Victal 2022-12-06tests: docker-system: Increase image size....* gnu/tests/docker.scm (run-docker-system-test)[vm]: Increase 'disk-image-size'. Ludovic Courtès 2022-06-24tests: docker: Relax marionette timeout....The tests would otherwise fail on an old desktop. * gnu/tests/docker.scm (run-docker-test) <make-marionette>: Specify a timeout of 60 s. (run-docker-system-test) <make-marionette>: Likewise. Maxim Cournoyer 2021-12-23tests: docker: Fix it....The docker tests are broken because the docker overlay doesn't support running on our own storage overlay. Use the new <virtual-machine> volatile? field to spawn a VM with a persistent storage and no overlay. * gnu/tests/docker.scm (run-docker-test): Add the docker-tarball to the gc roots as the host store is not shared anymore. Spawn a VM without volatile storage. (run-docker-system-test): Ditto. (%test-docker-system): Adapt it to use the image API. Mathieu Othacehe 2021-09-26tests: Reduce boilerplate for users of 'system-test-runner'....* gnu/tests/audio.scm, gnu/tests/base.scm, gnu/tests/ci.scm, gnu/tests/cups.scm, gnu/tests/databases.scm, gnu/tests/desktop.scm, gnu/tests/dict.scm, gnu/tests/docker.scm, gnu/tests/file-sharing.scm, gnu/tests/ganeti.scm, gnu/tests/guix.scm, gnu/tests/ldap.scm, gnu/tests/linux-modules.scm, gnu/tests/mail.scm, gnu/tests/messaging.scm, gnu/tests/monitoring.scm, gnu/tests/networking.scm, gnu/tests/nfs.scm, gnu/tests/package-management.scm, gnu/tests/reconfigure.scm, gnu/tests/rsync.scm, gnu/tests/security-token.scm, gnu/tests/singularity.scm, gnu/tests/ssh.scm, gnu/tests/telephony.scm, gnu/tests/version-control.scm, gnu/tests/virtualization.scm, gnu/tests/web.scm: Remove (mkdir #$output) (chdir #$output) and pass #$output as argument to 'system-test-runner'. Ludovic Courtès 2021-09-25tests: Adjust to SRFI-64 as found in Guile 3.0.7....In Guile 3.0.7, 'test-runner-current' is set to #f upon 'test-end'. Consequently, the previous strategy, where we'd call 'test-runner-current' after 'test-end', no longer works. Instead, set the test runner in each test right before 'test-begin'. * gnu/build/marionette.scm (system-test-runner): New procedure. * gnu/tests/audio.scm (run-mpd-test): Replace (exit (= ...)) idiom by (test-runner-current (system-test-runner)). * gnu/tests/base.scm (run-basic-test) (run-cleanup-test, run-mcron-test, run-nss-mdns-test): Likewise. * gnu/tests/ci.scm (run-laminar-test): Likewise. * gnu/tests/cups.scm (run-cups-test): Likewise. * gnu/tests/databases.scm (run-memcached-test) (run-postgresql-test, run-mysql-test): Likewise. * gnu/tests/desktop.scm (run-elogind-test): Likewise. * gnu/tests/dict.scm (run-dicod-test): Likewise. * gnu/tests/docker.scm (run-docker-test): Likewise.

Ludovic Courtès 2021-04-12tests: docker: Increase VM building memory size to 1024MiB....This fixes the following error when running the "docker-system" test: In ice-9/ftw.scm: 553:30 1 (_ #<directory stream db6660>) In unknown file: 0 (readdir #<directory stream db6660>) ERROR: In procedure readdir: In procedure readdir: Cannot allocate memory * gnu/tests/docker.scm (%test-docker-system): Bump image building VM memory size to 1024 MiB.
