• NixOS Grub Theme Feb 21, 2026
  Grub theme is a nice way to make unique appearance of your boot screen. There are quite many of cool available themes out there , but how do we install them? After all, NixOS takes a different approach in system configuration. If you just download and put the theme in /boot imperatively, then set the theme in grub.cfg, it will work until the next NixOS generation will substitute your current one. grub.cfg file is updated every switch, because NixOS has to add new generation entries to it, subsequently overwriting all the imperative changes you introduced to the file. We have to express this piece of configuration declaratively.
