  1. Infinito.Nexus 12.0: From a Single Server to a Scalable Sovereign Cloud

    Infinito.Nexus 12.0 is one of the most significant releases in the project’s history. Until now, Infinito.Nexus focused primarily on automating complete open-source environments on a single Docker Compose host. Version 12.0 introduces Docker Swarm as a second deployment mode, enabling applications to run across multiple servers, scale horizontally and recover from node failures. This release combines capabilities that are rarely delivered by one automation platform: More than 75 automatically deployable open-source applications One Single Sign-On experience backed by a unified user database Horizontal scaling across multiple cloud servers Automated backup and continuously tested disaster recovery Support across Debian, Arch Linux and RHEL-family distributions Filesystem-independent operation across ext4, btrfs and ZFS Together, these changes transform Infinito.Nexus from an application installer into a comprehensive foundation for scalable, sovereign cloud infrastructure.

  2. Package management is one of those things every Linux admin should know cold.

    Search for a package: dnf search packagename
    Install it: dnf install packagename
    Check what's installed: rpm -qa | grep packagename
    Remove it cleanly: dnf remove packagename

    Your package manager is your best friend. Treat it accordingly.

  4. New info and links on sketchesfromahomelab.com/artic

    - A patched kernel for RHEL systems is now available!
    - Added links to the original 2017 commit introducing the #CopyFail bug and to the patch fixing it. Also included a list of the Linux kernel versions containing the patch. Hopefully this will help those that compile their own kernels!
    - Added a link to GrapheneOS's analysis that Android is NOT vulnerable to Copy Fail due to its extensive use of SELinux and its prohibition on setuid/setgid binaries. I know a lot of people were concerned about Android devices, especially older ones, so this is welcome news.

    People needing more information about the patched RHEL kernel can go to:

  5. Fresh gist: mitigating CVE-2026-31431 ("Copy Fail") on RHEL 8/9/10 with a tiny Ansible playbook.

    It blacklists algif_aead via a kernel boot arg (initcall_blacklist=algif_aead_init), reboots only when needed, and asserts the mitigation actually stuck after reboot. Idempotent & safe to re-run.

  6. Thanks to @adamw, who dared to suggest we try it, we now have a small patch for #virtualenv in #Fedora to enable creation of #Python 3.6 virtual environments.

    Hence, you can use #tox to test your code on Python 3.6 to 3.15, without the need for nasty hacks -- github.com/tox-dev/tox/issues/

    Supporting testing on 3.6 is important to us, as many developers targeting #RHEL 8 still need to support it. (Python 3.6 is the new Python 2.6.)

    Anyway, test it out:
