Jan Grosser 06b44e415b Use AppImage of logseq 
Logseq relies on an older version of electron. Therefore, there are
often problems with the Nix package.

It is easier to use the AppImage and to identify possible alternatives.

NixOS Configuration Files wit Flakes, Home-Manager

Description

My NixOS configuration repository

Install a New Host

  1. Install NixOS with graphical ISO image (e.g. GNOME). During the installation the desktop environment can be choosen.
  2. Reboot into NixOS
  3. Edit /etc/nixos/configuration.nix with sudoedit
    • Change hostname
    • Enable flakes by adding the line nix.settings.experimental-features = [ "nix-command" "flakes" ];
    • Install tmux, neovim, git by adding them to environment.systemPackages = with pkgs; [
  4. Apply changes: sudo nixos-rebuild switch and reboot
  5. Clone NixOS config repository to /home/$USER/nixos:
cd $HOME
git clone https://git.plueschbit.de/jan/nixos-conf ~/nixos
  1. Add the new host to repository
    • Create ~/nixos/hosts/$HOSTNAME
    • cp /etc/nixos/*.nix $HOSTNAME/.
    • Edit ~/nixos/flake.nix and add section for new host
    • Stage new config files: git add flake.nix hosts/$HOSTNAME/*. Otherwise, nixos-rebuild will refuse to work with the files.
  2. Apply config: sudo nixos-rebuild switch --flake ~/nixos/#<host>

Update Packages on a Host

Update of the file flake.nix:

cd ~/nixos
sudo nix flake update

Then, perform nixos rebuild:

sudo nixos-rebuild switch --flake ~/nixos/#<host>

Upgrading to a new NixOS channel

In flake.nix the channel is set to unstable. Therefore, there is no need to upgrade the channel.

Garbage Collection

List all generations:

sudo nix-env --list-generations --profile /nix/var/nix/profiles/system

Keep e.g. the last five generations and perform garbage collection:

sudo nix-env --delete-generations +5 --profile /nix/var/nix/profiles/system
sudo nix-collect-garbage
