In episode 657 of BSD Now, titled 'Hibernation is a Long Sleep,' hosts Jason Tubner and Ruben Shea dive into the growing risks of technology dependence, particularly in enterprise storage, with a focus on European digital sovereignty. The episode opens with a deep dive into an article from Clara Log on the structural costs of proprietary storage stacks, highlighting how vendor lock-in, data gravity, and feature premiums create long-term financial and operational risks. The hosts advocate for open source solutions—especially OpenZFS—as a way to regain control, ensure portability, and maintain jurisdictional compliance. They also discuss practical implementations, including hierarchical jails using Podman and native FreeBSD jails, and the feasibility of running CUDA-enabled AI workloads on FreeBSD 15 via Linux emulation. Other topics include a bidirectional PFSense/OpenSense firewall migration tool, a peculiar SYN attack from Brazilian IPs with high TTL values, and the surprising revelation that blocking high-TTL packets inadvertently cut off Windows users. The episode closes with a celebration of OpenBSD’s delayed hibernation feature for AMD64 laptops, a battery-saving innovation for travelers. Throughout, the hosts emphasize automation, open systems, and resilience in the face of increasing complexity and geopolitical risk.
Open source storage like OpenZFS is critical for digital sovereignty, offering control, portability, and resistance to vendor lock-in.
High-TTL SYN attacks may originate from compromised Windows systems, and filtering them can block legitimate traffic—highlighting trade-offs in security decisions.
FreeBSD 15’s Linux compatibility layer enables running AI workloads like Llama CPP with CUDA, proving non-Linux Unix systems are viable for modern AI.
Hierarchical jails combining Podman and native FreeBSD jails offer powerful isolation and automation potential for secure, nested environments.
Delayed hibernation in OpenBSD AMD64 laptops prevents battery drain during long travel, a practical feature for mobile users.

The Real Cost of Technology Dependence
“In practice, this form of technology dependence manifests across several layers. Economic, proprietary APIs, data formats, and migration tooling creating switching costs that allow price increases to outpace general inflation.”
OpenZFS as a Sovereign Storage Foundation
“With open source storage, you can change integrators or support partners without replatforming your data. Reducing technology dependence does not mean eliminating vendors. It means designing storage architectures where control, portability, and lifecycle decisions remain in your hands.”
Hierarchical Jails with Podman and FreeBSD 15
A technical deep dive into creating nested jail structures using Podman containers as the first layer and native FreeBSD jails as the second. The guide demonstrates how to leverage FreeBSD’s kernel-level isolation for secure, scalable environments.
FreeBSD 15 with Linux Compatibility and CUDA
“The number of times I've entered a balked state because in a past life I bought an NVIDIA card instead of something which I should have bought. It's never once had a problem with it on FreeBSD. It just works.”
Firewall Migration and the SYN Attack Mystery
“It still doesn't answer why this is being done though. Weird. Update on Thursday, 29th of January. Microsoft has a TTL of 128. Of course it does. Oh dear.”
