Domen Kozar has announced the launch of NixOS 16.03. In NixOS, the entire operating system, including the kernel, applications, system packages and configuration files, are built by the Nix package manager. Nix stores all packages in isolation from each other; as a result there are no /bin, /sbin, /lib or /usr directories and all packages are kept in /nix/store instead. NixOS 16.03 is a fairly minor upgrade for the project, featuring updates to the kernel and systemd along with improvements to the Nix package manager. “NixOS community is proud to announce the third NixOS stable release ‘Emu’ 16.03. This is a low profile release, but it contains many small improvements. We had 10,567 commits from 448 contributors in this release spanning over six months. The release brings many improvements including Nix 1.12.2, systemd 229, kernel 4.4 and many packages updates.“
GNU Guix is a functional package manager for the GNU system. In addition to standard package management features, Guix supports transactional upgrades and roll-backs, unprivileged package management, per-user profiles, and garbage collection. Guix uses low-level mechanisms from the Nix package manager, except that packages are defined as native Guile modules, using extensions to the Scheme language. GuixSD offers a declarative approach to operating system configuration management, and is highly customizable and hackable.
As of version 0.10.0, the Guix System Distribution can be installed on an i686 or x86_64 machine. It uses the Linux-Libre kernel and the GNU Shepherd init system. Alternately, its package manager, GNU Guix, can be installed as an additional package manager on top of an installed Linux-based system.
It is also possible to use Guix on top of an already installed GNU/Linux system, including on mips64el and armv7.
Ludovic Courtès has announced the release of a new version. It offers reproducible builds for several key packages, plus the GNOME desktop environment and over 600 new packages in the project’s repositories. “It’s been almost five months since the previous release, and many things happened! The highlights include: Our grafting mechanism for security updates has been fixed to be generally applicable. Read this post for more information on the challenges behind this. Substitutes are now fetched by default over HTTPS and from a faster mirror. A number of packages have been made bit-for-bit reproducible, including glibc, Perl, Emacs packages, and Python packages. This work was simplified by Guix challenge and by the new –check and –rounds build options, and also by the insight gathered from other reproducible builds efforts. GNOME is now available, via the gnome-desktop-service procedure. 639 new packages, about as many package updates, greatly simplified by the addition of new importers and auto-updaters. A wealth of bug fixes, documentation improvements, Emacs niceties, and more!“
