Guix System Distribution
Guix System (formerly Guix System Distribution, or GuixSD) is a Linux-based, stateless operating system that is built around the GNU Guix package manager. The operating system provides advanced package management features such as transactional upgrades and roll-backs, reproducible build environments, unprivileged package management, and per-user profiles. It uses low-level mechanisms from the Nix package manager, but packages are defined as native Guile modules, using extensions to the Scheme language.

Development Release: NetBSD 8.1 RC1 |
|
Martin Husemann has announced the availability of a new release candidate for NetBSD 8.1. The new release candidate ships with CPU vulnerability workarounds, a new wireless driver and several performance improvements. Husemann writes: "The NetBSD Project is pleased to announce NetBSD 8.1 RC1, the first (and hopefully final) release candidate for the upcoming NetBSD 8.1 release. Over the last year, many changes have been made to the NetBSD 8 stable branch. As a stable branch the release engineering team and the NetBSD developers are conservative with changes to this branch and many users rely on the binaries from our regular auto-builds for production use. Now it is high time to cut a formal release, right before we go into the next release cycle with the upcoming branch for NetBSD 9. Besides the workarounds for the latest CPU specific vulnerabilities, this also includes many bug fixes and a few selected new drivers. For more details and instructions see the 8.1 RC1 announcement." Additional details can be found in the CHANGES-8.1 file. Download (SHA512) links: NetBSD-8.1_RC1-amd64.iso (722MB), NetBSD-8.1_RC1-i386.iso (684MB). |

BSD Release: NetBSD 8.0 |
|
The NetBSD team has announced a new version of their project's highly portable operating system. The new version, NetBSD 8.0, included support for USB 3, reproducible builds, in-kernel audio mixing and address layout randomization for improved security. "USB stack rework, USB3 support added. In-kernel audio mixer (audio_system(9)). Reproducible builds (MKREPRO, see mk.conf(5)). Full userland debug information (MKDEBUG, see mk.conf(5)) available. While most install media do not come with them (for size reasons), the debug and xdebug sets can be downloaded and extracted as needed later. They provide full symbol information for all base system and X binaries and libraries and allow better error reporting and (userland) crash analysis. PaX MPROTECT (W^X) memory protection enforced by default on some architectures with fine-grained memory protection and suitable ELF formats: i386, amd64, evbarm, landisk, pmax. PaX ASLR (Address Space Layout Randomization) enabled by default on: i386, amd64, evbarm, landisk, pmax, sparc64. Position independent executables by default for userland on: i386, amd64, arm, m68k, mips, sh3, sparc64." Further details can be found in the project's release notes.

Development Release: NetBSD 8.0 RC2 |
|
Martin Husemann has announced the availability of the second (and probably final) release candidate for NetBSD 8.0, a highly portable operating system available for dozens of processor architectures. The new release candidate fixes a number of issues that existed in the previous snapshot and includes kernel security fixes for CPU bugs. "The NetBSD Project is pleased to announce NetBSD 8.0 RC 2, the second (and hopefully final) release candidate for the upcoming NetBSD 8.0 release. Unfortunately the first release candidate did not hold up in our extensive testing (also know as eating our own dog food): many NetBSD.org servers/machines were updated to it and worked fine, but the auto build cluster, where we produce our binaries, did not work well. The issue was tracked down to a driver bug (Intel 10 GBit Ethernet), only showing up in certain configurations, and it has been fixed now. Other security events, like the new FPU related exploit on some Intel CPUs, caused further kernel changes, so we are not going to release NetBSD 8.0 directly, but instead provide this new release candidate for additional testing. " More information can be found in the project's release announcement. Download (SHA512): NetBSD-8.0_RC2-amd64.iso (716MB), NetBSD-8.0_RC2-i386.iso (677MB). |
