 ### TODO
 
 - Make rofi power menu work by removing password requirement from shutdown, reboot, etc., which is normally done with `visudo` (see [this Stack Overflow thread](https://askubuntu.com/a/168885) and [Nix `sudo` option](https://search.nixos.org/options?channel=22.05&from=0&size=50&sort=relevance&type=packages&query=sudo).
-- Package safe poweroff bash script required by rofi power menu
 - Theme GRUB
 - Find out how handling multiple hosts works so both desktop and ThinkPad configurations are buildable from flake
 - Load in vim configuration
