Steps to replicate the system configuration starting from a fresh NixOS installation:

1. install git: sudo nano /etc/nixos/configuration.nix => sudo nixos-rebuild switch
2. clone repository: cd ~ ; git clone https://github.com/siphc/nixos-configuration.git (note that you won't have ssh by this stage!)
3. download source code of required packages (dwm, st, slstatus) and copy configuration files over (TODO: this task is automate-able, so we can write a shell script that accomplishes this)
4. change users.users.* and "nixos-config=* in nix.nixPath to your own username, of course.
5. IMPORTANT: change system.stateVersion to your own version AS OF TIME OF INSTALL as described in /etc/nixos/configuration.nix.
6. nixos-rebuild switch -I nixos-config=/home/[USER]/nixos-configuration/configuration.nix
7. ~/nixos-configuration/initsetup.sh
8. reboot.

Optionally you can do a manual patch in slstatus/util.c where you change the prefix_1024 values in fmt_human to single characters i.e. K, B, G. I could make a patch but I'm too lazy.

Steps to upgrade nixpkgs channels: I don't trust system.autoUpgrade.enable, so we have to do this manually twice a year.

1. sudo nix-channel --add https://channels.nixos.org/channel-name nixos, change channel-name to a desirable channel, like nixos-25.11 or nixos-unstable.
2. sudo nixos-rebuild switch --upgrade Both commands have to be ran with sudo to make sure that the channel is correctly set in the configuration file (as channels are set per user). Pretty sure this recompiles firefox like 4 times, so you'll need to wait a bit.

TODO:

• All three suckless packages can be added as Git submodules... Will get to that the next time I have to reinstall my system.
• There is also a (one-line) patch needed to fix window borders being transparent. It is called fixborders. I have manually applied it for now but I will get to automating that when I have the time.
  • This patch makes it so that you have to login twice SOMETIMES (the first time it logs out automatically). I do not know why. The fix works though
• It is best to set up a cronjob that runs sudo nixos-rebuild switch --upgrade every 24 hours or so, as the rebuild times are quite long if left neglected for a long time.
