John Baldwin, a long-time FreeBSD community member, has been elected to the FreeBSD Foundation Board. With a history dating back to his undergraduate years, Baldwin has contributed significantly to FreeBSD's development and community. His roles have included serving on core teams, release engineering, and the srcmgr team, as well as chairing the FreeBSD Journal's editorial board. Baldwin aims to strengthen the bond between the developer community and the Foundation, bringing his extensive experience and unique perspective to the board. His election is expected to enhance the Foundation's support for the FreeBSD Project.
The FreeBSD Foundation has announced that applications for travel grants to attend EuroBSDCon 2025 are now open. These grants are designed to assist FreeBSD developers and advocates with travel expenses for conferences related to FreeBSD development. The deadline for applications is August 5, 2025. Additionally, the Foundation offers travel grants for other technical events, provided that attendance benefits the FreeBSD Project and Community. Applications for these grants must be submitted at least seven weeks prior to the event.
How to use Podman hooks to mount ZFS datasets into containers, and cleaning up on exit, ensuring datasets are properly unmounted. This setup is ideal for managing persistent data in ephemeral containers, such as databases.
FreeBSD version 14.3 is available, Reliable ZFS Storage on Commodity Hardware, My website is ugly because I made it, Semi distributed filesystems with ZFS and Sanoid, April 2025 Laptop Support and Usability Project Update, UDP sockets instead of BPF in dhcpd(8), and more.
The FreeBSD Foundation has initiated a project to enable Software Bill of Materials (SBOM) for FreeBSD, commissioned by the Sovereign Tech Agency. Running from April to December 2025, the project aims to enhance tooling and processes for SBOMs, which are crucial for improving software supply chain visibility and security. Key goals include developing tools to merge provenance data, parse and inspect the FreeBSD source tree, and extend package management capabilities. The project is driven by user demand and regulatory requirements, with a focus on automation and long-term maintenance. The Foundation will provide periodic updates to the community as the project progresses.
The FreeBSD Foundation has initiated a project to bolster security in FreeBSD Ports and Packages, commissioned by the Sovereign Tech Agency. Running from April to December 2025, this project is part of a broader strategic initiative to advance Zero Trust builds, SBOM adoption, and CI/CD automation. Key goals include migrating from the VuXML vulnerability database to the industry-standard OSV, improving CI tooling for FreeBSD Ports, and developing a package audit backend. These enhancements aim to speed up release updates and strengthen security measures, with periodic updates shared with the community as the project progresses.
The article discusses the use of OpenZFS as a storage backend for virtual machines, highlighting its reliability and performance benefits. It emphasizes the importance of hardware selection, including the use of enterprise-grade SSDs for long-running workloads and the consideration of write endurance and drive size. The article also covers the significance of pool topology, recommending mirror vdevs for optimal performance. Additionally, it explores the impact of recordsize tuning on performance, suggesting specific values for different workloads.
The latest update to DragonFly BSD introduces new 'proxy' and '-proxy' options for the ifconfig utility. The 'proxy' option is now enabled by default, allowing IPv6 interfaces to respond to neighbor solicitations when forwarding is active. Users can disable this feature with the '-proxy' option, reverting to the previous default behavior. This change, implemented in May, enhances the network configuration capabilities of DragonFly BSD.
