Arch Linux
What I use
I use WM (Window Manager). My choice is Hyprland. To have a status bar, I chose to use Waybar. As a terminal app, I use Alacritty with tmux.
Replicating NixOS positives in Arch
In order to have a fail-safe, which would save me from update issues, I could use something like timeshift or snapper. These are tools from Linux Mint and openSUSE respectively.
One can also manage dotfiles using chezmoi. I also find this tool called yadm. It seems like it will work for my use-case.
