If you want to try, add the following code to your configuration.nix file. Specialisations can use any argument that would work in the top-level configuration, so we are not limited in terms of what can be changed.
Our user Paul will need an extra system-wide package, for example dune-release. Auto login at boot will be set for both users in their own specialisations. This will be quite awesome :)Īs an example, we will create two specialisations, one having the user Chani using the desktop environment Plasma, and the other with the user Paul using the desktop environment Gnome. In a follow-up blog post, I will describe a secure setup using multiple encrypted partitions with different passphrases, all managed using specialisations with a single NixOS configuration.

This asks the full path of the test program named hello and compares both.

While your users would only exist in one specialisation at a time, both users’ data are stored on the same partition, so one user could be exploited by an attacker to reach the other user’s data. In the serial console, upon reboot, boot on bsd.rd (the OpenBSD installer. However, by default, such a setup would be more practical than secure. This would create a hard separation without using multiple operating systems. Specialisations can have their own users, services, packages and requirements. We can push the idea further by using a single computer for professional and personal use. You can also define a specialisation which will boot into a different kernel, giving you a safe opportunity to try a new version while keeping a fallback environment with the regular kernel. I choose the eGPU specialisation in my boot menu, and it just works. With NixOS, when I need my external GPU, I connect it to my computer and simply reboot my system. This is common for people with external GPUs (Graphical Processing Unit), and the reason why I first used specialisations. Specialisations can create a new boot entry you can use when starting your computer with your specific hardware connected. You may have hardware occasionally connected to your computer, and some of these devices may require incompatible changes to your day-to-day configuration. NixOS has a unique feature that solves this problem in a clever way - NixOS specialisations.Ī NixOS specialisation is a mechanism to describe additional boot entries when building your system, with specific changes applied on top of your non-specialised configuration. I often wished to be able to define different boot entries for different uses of my computer, be it for separating professional and personal use, testing kernels or using special hardware.

I'm grateful to be allowed to publish NixOS related content there, but also to be able to reuse it here!Īfter the publication of the original post, the NixOS wiki got updated to contain most of this content, I added some extra bits for the specific use case of "options for the non-specialisation that shouldn't be inherited by specialisations" that wasn't convered in this text.
