The UAPI Boot Loader Specification defines conventions that let multiple operating systems and bootloaders share boot config files. So far, only systemd-boot implements it - and it’s UEFI-only by design.As a result, hybrid UEFI/BIOS images require maintaining (and keeping in sync) two sets of bootloader configs: one for systemd-boot, and one for a …

I overview how OS management is done at Meta. We run millions of Linux servers and we have to make sure that OS gets updated on all of them in a given period of time. To do that we developed several products: MetalOS (Image based version of CentOS), Antlir (image builder) and Rolling OS Update (a service that keeps a set of DNF repos in sync with u…

Updates are a critical piece of managing your fleet of devices. Nowadays, Yocto-based distributions can utilize layers for well-established update mechanisms. But, did you know that recent releases of Yocto already come with a simple update mechanism?Enter systemd-sysupdate: a mechanism capable of automatically discovering, downloading, and install…

`test.thing` is a VM runner which targets guests using an API defined by systemd. It started after a conversation at devconf about turning `mkosi qemu` into a library. A quick intro.~~composefs is an approach to image-mode systems without the disk images. Files are stored in a de-duplicated content-addressed storage with integrity guaranteed throug…

S3NS is a trusted cloud operator that self-hosts Google Cloud infrastructure in France, targeting the SecNumCloud certification, the most stringent Cloud certification framework. SecNumCloud includes strict legal and operational constraints. To manage these systems securely and reproducibly, we’ve built a family of dedicated administration terminal…

With Bootable Containers (bootc), we can place the operating system files inside a standard OCI container. This lets users modify the content of the operating system using familiar container tools and the Containerfile pattern. They can then share those container images using container registries and sign them using cosign.Using composefs and fs-ve…

Introduce ue-rs, a fresh project that aims to be a drop-in reimplementation of update engine, written in Rust.The goal of ue-rs is to have a minimal, secure and robust implementation of update engine, required by A/B update mechanism of Flatcar Container Linux.

In the Linux world there are several tools and technologies to encrypt data on a hard drive, most falling into one of two categories: block device encryption (like LUKS) or stacked filesystem encryption (like EncFs or gocryptfs). This presentation will introduce Dirlock, a new tool that belongs to a third category: native filesystem encryption, usi…

Traditional package updates using tools like RPM or Zypper can introduce risks, such as incomplete updates or accidentally breaking the running system. To overcome these challenges, we developed **container-snap**, a prototype plugin designed to deliver atomic OS updates—updates that are fully applied or rolled back without compromising the system'…

File descriptors for processes on Linux have been available for quite some time now. Userspace has adapted them widely.Over the last two years or so we've extended the abilities of pidfds significantly.

Unfortunately, until very recently that required one to then maintain their own build and deployment pipeline for the packages, at least until the changes made …

GNOME has collected some very old code over the years. During the recent GNOME 49 release, we've made some drastic cleanups. Most visibly, we've dropped support for X11 and gained many dependencies on systemd.

Coredumping on Linux has long been a nightmare. Currently two modes are supported:(1) Dumping directly into a file somewhere on the filesystem.(2) Dumping into a pipe connected to a usermode helper process spawned as a child of the system_unbound_wq or kthreadd.For simplicity I'm mostly ignoring (1). There's probably still some users of (1) out the…
