The Dutch government is building a work environment for its civil servants on NixOS, a Linux distribution, in order to remove Microsoft and other US vendors from its stack. It's FOSS reported on 26 September 2026 that a July directive from the Interdepartmental Commission for Government Business Operations (ICBR) made the project an official mandate. The project is called DAWO, short for Digitaal Autonome Werkomgeving Overheid, and the directive assigns its execution to SSC-ICT, DICTU and DUO-ICT, the central government's three major IT service providers itsfoss.com.
daily.dev summarised the scope as a full stack: operating system, office tools, collaboration, cloud, IT management and AI daily.dev - Dutch Government…. Eight municipalities are piloting it through the Association of Netherlands Municipalities (VNG), on decommissioned laptops daily.dev - Dutch Government…. Boing Boing reported that the developers hope to ship a stable version in 2027 boingboing.net. Trending Topics, citing Yahoo Tech, reported that there is no timeline yet for a nationwide rollout trendingtopics.eu. XDA and Boing Boing both credit the underlying reporting to Tweakers, a Dutch technology site, which spoke to the developers xda-developers.comboingboing.net. The piece is correspondingly thin: a mandate, a pilot, a target year, and the account of one outlet relayed by several others.
Corporate parentage, not licence, decided the operating system
It's FOSS reported that the team chose NixOS because it is a Dutch project that no company owns or controls. It also reported that openSUSE and Fedora were considered and disqualified over their commercial ties, openSUSE to SUSE and Fedora to Red Hat, which is owned by US-based IBM itsfoss.com. Boing Boing reported that NixOS originated in a package manager created at Utrecht University boingboing.net.
Our read is that this matters for anyone selling enterprise Linux to European governments. Two open-source distributions were excluded because of who stands behind them, not because of their licences.
The same logic reaches code hosting. DAWO's code sits on Forgejo and Codeberg rather than GitHub daily.dev - Dutch Government….
Reproducibility is the cost argument, on hardware Windows 11 drops
The engineering case rests on how Nix installs software. According to It's FOSS, Nix handles configuration through its own functional language and installs each package into an isolated directory with immutable, signed contents, so a working setup can be reproduced across machines itsfoss.com. Rutger Putter, one of the named members of the development team, estimates that 80 to 90 percent of a configuration carries over between deployments itsfoss.com. Trending Topics reported that NixOS runs on older hardware that Windows 11 no longer supports trendingtopics.eu. That is how the pilots can use laptops that would otherwise be retired.
Trending Topics also listed where the project can fail trendingtopics.eu:
- legacy applications that run only on Windows;
- document exchange with Microsoft Office;
- training thousands of civil servants;
- drivers across varied hardware;
- security certification;
- the unresolved question of who maintains and pays for the system long term.
The directive is addressed to central-government providers, but the pilots run in municipalities. Our read is that municipal results will be an imperfect guide to a central-government rollout.
The trigger is disputed and the precedent is mixed
Every account traces DAWO to US sanctions on the International Criminal Court in early 2025. Tweakers' machine-translated summary of Victor Gevers, an innovation manager and security expert on the project, was carried by XDA. It said the Dutch government "realized that access to many essential services depends on the policy direction of the US government." It added: "There are now signs that the Trump administration is preparing broader sanctions against the ICC." xda-developers.com Microsoft disputes the account that the court's chief prosecutor lost access to its services. Trending Topics also reported that Microsoft now offers European customers sovereignty options such as an EU Data Boundary trendingtopics.eu.
The Next Web wrote that government Linux migrations have "a long and largely disappointing history." It said most have reversed under compatibility problems, vendor pressure and legacy-software path dependence thenextweb.com. The publication then argued that France is an exception. It cited the Gendarmerie nationale, whose Ubuntu-based GendBuntu ran on 103,164 workstations by June 2024, 97% of the force's estate. The Gendarmerie's figures show about €2 million a year in licensing savings and an estimated 40% lower total cost of ownership thenextweb.com.
The French comparison is itself contested. The Next Web reported that no Linux distribution was named in France's public announcement and that ministries keep flexibility to choose thenextweb.com. Boing Boing reported that DINUM, France's interministerial digital directorate, is moving 250 employees to Linux workstations using NixOS boingboing.net.
A public-sector worker commenting on The Register described most of his organisation's systems, including Outlook and Teams, as reachable through a browser from Linux. In that setting, he wrote, "just swapping the OS for endpoints doesn't make that much difference" forums.theregister.com. Our read is that the dependency DAWO has to break sits as much in the cloud and collaboration layers as on the desktop.
The Netherlands has been here before. In December 2007 The Register reported that the Dutch economic affairs ministry said parliament had approved a plan mandating open standards and open source software government-wide forums.theregister.com.
On this evidence, the milestone that would change the assessment is the promised stable release, with document exchange with Microsoft Office working, after the eight municipal pilots.
