FreeBSD Developer Summit, September, 2026

This page describes the September 2026 FreeBSD Developer Summit, colocated with EuroBSDCon 2026, which takes place in Brussels, Belgium from September 09 to 10, 2026. This is a by-invitation event.

Also consider attending the Hackathon in Berlin the weekend before.

Registration

Registration is a two step process:

1) you must register for the Devsummit at the EuroBSDcon page and pay the devsummit fee to attend.

2) FreeBSD committers add themselves or any of their guests to this wiki page below. 👇🏻

/!\ Note: Paying for the devsummit only allows entry to the devsummit. Other activities and the main EuroBSDcon conference must be paid separately and are not included in the devsummit fee.

Event: EuroBSDcon Devsummit 2026

Schedule

{i} This year, we will have an extra day after the two days of the devsummit. This page covers only the devsummit part. Details about what, where, and when are announced as on the EuroBSDcon schedule. Plan your travels accordingly to arrive earlier in the week of EuroBSDcon to be able to attend all these events.

The FreeBSD developer summit takes place as part of the EuroBSDCon event. Many developers will arrive on the night before and meet for dinner and drinks before things kick off. Most developers will stay on through EuroBSDCon to give and attend talks or tutorials. It is an excellent conference--a good FreeBSD developer showing has countless benefits, not least the opportunity to tell the world what we're doing.

Detailed Schedule will be updated as the event approaches. Check back for details.

Description

Slides, Notes

Live-patching for the FreeBSD kernel

FedericoAngelilli

The goal is adding a new kernel subsystem for hot-patching the running kernel code and maintaining high uptime. The patches will be delivered with normal .ko files, and we are also working on the related user-land utilities to build and use them.

The state of IM (Instant Messaging) on FreeBSD

Polarian

This talk will cover two topics, firstly it will run through the choices on IM on *BSDs. Then I will be discussing what I have been working on.

Jail implementation details (standby talk)

KyleEvans

Some jail implementation details if the audience is interested in it. If not, we cut it or let someone else take the slot. But if there *is* interest, there will be content to show.

if_pair(4) – Fast IP point-to-point link for vnet jails

Jan Bramkamp

if_pair(4) is an IP-level companion to if_epair(4), providing fast point-to-point links between vnet jails without the overhead of Ethernet.

Lightning talks

multiple

Your talk is too short but still worth presenting? Then give a lightning talk, even slides are optional. Show us your work, explain your idea, excite the audience. Current topics: the current state of the default partition layout for GPT and ZFS, bootloader updates, documentation for the aspiring operator.

Foundation Update and Open Discussion on Development Priorities

Keys to survival

BenedictReuschling

This is a single/multiplayer simulation of group survival. I'll bring all the materials, but need some volunteers to make it work. Aha moments guaranteed!
