Devices

The devices directory contains the core definitions for multiple PCs and various other devices. To add a new device, simply create a configuration file for it (name of the file/directory must be the same as the hostname of the device) and write down the configuration using the options of the desired modules from the modules directory, or add your own configuration modules using the imports keyword. You can also use the keyword format to generate a particular type of image for that device (Eg. iso, generated using nixos-generators). Optionally, add user-specific configuration in users. Then, run the command nixos-rebuild switch --flake .#HOSTNAME and let Nix do all the work for you!

Additional Options

These are the options that can be used in addition to the ones exposed by the modules:

• description: System Description (to add to config.system.name)
• timezone: System Time Zone - Ex. "Asia/Kolkata"
• locale: Default Locale - Ex. "IN"
• kernel: Linux Kernel to use (from pkgs.linuxKernel.packages.linux_${kernel}) - Ex. zfs
• kernelModules: Additional Kernel Modules (to add to config.boot.initrd.availableKernelModules) - Ex. [ "nvme" ]
• imports: Additional Configuration Files to import - Ex. [ ./hardware-configuration.nix ]
• format: Generates Output for Specified Target Format (See this for the list of supported formats)
• user or users (--> config.user.settings): Used to specify Device User/Multiple Users per Device - Ex. users = [ { name "1"; } { name = "2"; } ]
• update: Enable Automatic System Upgrades - Ex. weekly
• channel: Specify which Package Channel the system is built from - Ex. unstable

Warning

Specifying any other package channel apart from stable may be untested and cause breakage
