## disko and nixos-anywhere: Remote installation
* Introductory presentation: https://pad.lassul.us/cccamp-workshop
* disko: https://github.com/nix-community/disko
* See [hosts/yodaYoga/disko-config.nix](hosts/yodaYoga/disko-config.nix)
* nixos-anywhere: https://github.com/numtide/nixos-anywhere/
Install NixOS via SSH everywhere.
TODO. This is at low priority as I don't install new systems too often. And it is a quite fast process with the graphical NixOS installer.
There is a separate repository for these steps. Its README can be found here: https://codeberg.org/privacy1st/nixos-anywhere-example/src/template/README.md

# Cryptsetup can transparently forward discard operations to an SSD. This feature is activated by using the --allow-discards option in combination with cryptsetup open. Enabling discards on an encrypted SSD can be a measure to ensure effective wear leveling and longevity, especially if the full disk is encrypted. For an in detail discussion about the security implications, have a look at the cryptsetup FAQ and the man page of cryptsetup.
