- Install NixOS with ZFS as root filesystem This repo contains a minimal set of configuration for installing NixOS, using ZFS as root filesystem.
ZFS is a modern filesystem with many features such as snapshot, self-healing and pooled storage, see [[https://openzfs.org/wiki/Main_Page#Introduction_to_OpenZFS][Introduction]] for details.
For using this repo on your computer, see [[https://openzfs.github.io/openzfs-docs/Getting%20Started/NixOS/Root%20on%20ZFS.html][Documentation]].
Upon initial installation, only the bootloader, mountpoints and root password are configured.
- Refer to =man configuration.nix= for available options;
- Search for available packages with [[https://search.nixos.org/packages][Package Search]];
- Search for options with [[https://search.nixos.org/options][Option Search]].
[[https://codeberg.org/m0p/dotfiles][My personal dotfiles repo]] contains an example of desktop configuration based on sway, tmux and Emacs.
