These provide users with a way to control background processes, commonly refereed as daemons , as well as ways of controlling the setup of files. For example, openssh-service-type is a service which controls a SSH daemon. In contrast, etc-service-type is a service that populates the contents of the /etc directory. One peculiarity of Guix services is that it's customary to provide Scheme bindings for the different fields. By that I mean that the different fields of the configuration of most services will be a... ## 'guix substitute' and 'guix pull' Vulnerabilities DevFeed: ['guix substitute' and 'guix pull' Vulnerabilities]() Original publisher: [Read original article]() Author: Caleb Ristvedt Published: 2026-07-02T17:00:00Z Content type: release Language: en Sources: [GNU Guix -- Blog]() Topics: [Vulnerabilities](), [Security](), [upgrade]() Tags: [cve](), [mitm](), [root](), [security](), [security-advisory](), [upgrade](), [user](), [vulnerabilities]() ### AI overview The article details several security vulnerabilities in Guix substitute and guix pull, including remote privilege escalation, remote store corruption, possible disclosure of sensitive files, and file overwrite issues. It advises users to upgrade the Guix daemon and describes a regression affecting some unprivileged users. ### Source excerpt Several security issues (CVE IDs pending) have been identified in guix substitute , a helper utility invoked by guix-daemon , which enable a variety of harmful activities including remote privilege escalation to the build daemon user , remote store corruption , and potentially local disclosure of sensitive files accessible to the build daemon user. All systems are affected, whether or not guix-daemon is running with root privileges; the harm that can be done when guix-daemon runs without root privileges is more limited. You are strongly advised to upgrade your daemon now (see... ## One year with Codeberg DevFeed: [One year with Codeberg]() Original publisher: [Read original article]() Author: Ludovic Courtès Published: 2026-06-22T14:00:00Z Content type: article Language: en Sources: [GNU Guix -- Blog]() Topics: [pull-requests](), [hosting](), [issue tracking](), [decision-making](), [Git](), [forgejo]() Tags: [article](), [change](), [collaboration](), [community](), [decision-making](), [forgejo](), [issue-tracking](), [pull-requests](), [source]() ### AI overview Guix describes its migration to Codeberg for source code hosting, issue tracking, and pull requests after more than a decade using Savannah, email-based bug reports, patches, and Debbugs. The article discusses the reasons for the change, the project's collective decision-making process, and early takeaways after one year. ### Source excerpt A year ago, Guix migrated to Codeberg for source code hosting, issue tracking, and pull requests. This is a significant change for a project with more than 400 people contributing code each year, after more than decade hosting code at Savannah and dealing with bug reports and patches by email, tracked by a Debbugs instance . This article discusses the process that led to this change and lists some takeaways, a year later. The non-obvious choice For years before, the question of our choice of source code hosting and collaboration tools would regularly come up. However, with... ## Guix improves one-line deployment with more secure channel file downloads DevFeed: [Guix improves one-line deployment with more secure channel file downloads]() Original publisher: [Read original article]() Author: Ludovic Courtès Published: 2026-05-12T15:00:00Z Content type: article Language: en Sources: [GNU Guix -- Blog]() Topics: [Security](), [Deployment](), [Software](), [Bash]() Tags: [bash](), [deployment](), [reproducibility](), [research](), [security](), [software]() ### AI overview This article examines Guix one-line deployment commands and the security risks of downloading and executing arbitrary channel files. It introduces a feature for downloading channel files while addressing trust and security concerns. ### Source excerpt When offered the option to run other people's code, a prime consideration is often ease of deployment. While much progress has been made in support of rapid deployment, the security implications of those quick deployments is often overlooked. In this post, we look at a new feature of guix time-machine and guix pull in support of one-line deployment commands : the ability to download channel files, but without compromising on security. Sharing code The normal workflow to share software and make it easily deployable with Guix goes like this: someone puts their packager hat on and... ## The 64-bit Hurd is Here!

And most of you will have guessed, unless you skipped the title of this post, the rumored x86_64 support has landed in Guix! Here is a not-so-short overview of our Hurd work over the past 1.5 years: The build daemon fails when invoking guix authenticate on the Hurd bug was fixed. This was our most pressing problem as it meant that we could not keep... ## Result of Sustain and Strengthen Fundraising DevFeed: [Result of Sustain and Strengthen Fundraising]() Original publisher: [Read original article]() Author: Steve George Published: 2026-02-17T11:00:00Z Content type: news Language: en Sources: [GNU Guix -- Blog]() Topics: [Computing](), [FOSDEM]() Tags: [community](), [fosdem](), [fundraising](), [support]() ### AI overview GNU Guix reports raising EUR 11,378, or 75% of its EUR 15,000 annual fundraising goal, along with EUR 3,830 from Guix Days registrations.
