About the installation

This is hardware specific and can easily be changed by switching out hardware-configuration.nxi files.

I use a erase my darlings-like setup. My desktop pc uses an encrypted btrfs partition, which has subvolumes for nix store, games, home (snapshotted), srv (snapshotted), and var. The pi is similar, but with a single ext4 partition for all that. The root filesystem is a tmpfs, on which the partitions are mounted to achieve opt-in state.

I use home-manager as a standalone module, and, as such, i have to "manually" activate it. For this reason, i have a hook on loginShell that activates it, if not already active.

How to bootstrap

All you need is bash, nix, and git. Just nix-shell (or nix develop, if already on flakes), and you should be good to go.

nixos-rebuild --flake . To build system configuration

home-manager --flake . To build user configuration
