# Installs NixOS on a Hetzner server, wiping the server.
|
||||
#
|
||||
# This is for a specific server configuration; adjust where needed.
|
||||
#
|
||||
# Prerequisites:
|
||||
# * Update the script wherever FIXME is present
|
||||
#
|
||||
# Usage:
|
||||
# ssh root@YOUR_SERVERS_IP bash -s < hetzner-dedicated-wipe-and-install-nixos.sh
|
||||
#
|
||||
# When the script is done, make sure to boot the server from HD, not rescue mode again.
|
||||
|
||||
# Explanations:
|
||||
#
|
||||
# * Adapted from https://gist.github.com/nh2/78d1c65e33806e7728622dbe748c2b6a
|
||||
# * Following largely https://nixos.org/nixos/manual/index.html#sec-installing-from-other-distro.
|
||||
# * **Important:** We boot in legacy-BIOS mode, not UEFI, because that's what Hetzner uses.
|
||||
# * NVMe devices aren't supported for booting (those require EFI boot)
|
||||
# * We set a custom `configuration.nix` so that we can connect to the machine afterwards,
|
||||
# inspired by https://nixos.wiki/wiki/Install_NixOS_on_Hetzner_Online
|
||||
# * This server has 2 HDDs.
|
||||
# We encrypt all hard drives and put an LVM on it the main logical volume is mirrored
|
||||
# Storage scheme: `partitions -> dm-crypt -> LVM -> ext4`.
