this way we can easily use ip by hostname in other modules

-# Create host with disko-install
+# Create host with nixos-anywhere
-How to use disko-install is described here: https://github.com/nix-community/disko/blob/master/docs/disko-install.md
+We use a nixos-anywhere wrapper script to deploy new hosts.
----
+The wrapper script takes care of copying persistent host keys before calling nixos-anywhere.
-Here are the exact steps to get bakunin running:  
+
-First create machines/hostname/configuration.nix  
+To accomplish that boot the host from a nixos image and setup a root password.
-Add hosts nixosConfiguration in machines/configurations.nix  
-Boot nixos installer on the Machine.  
 ``` bash
-# establish network connection
+sudo su
-wpa_passphrase "network" "password" > wpa.conf
+passwd
-wpa_supplicant -B -i wlp3s0 -c wpa.conf
+```
-ping 8.8.8.8
-# if that works continue
 
-# generate a base hardware config
+After that get the hosts ip using `ip a` and start deployment from your own machine:
-nixos-generate-config --root /tmp/config --no-filesystems
 
-# get the infra repo
+``` bash
-nix-shell -p git
+# from infrastrucutre repository root dir:
-git clone https://git.dynamicdiscord.de/kalipso/infrastructure
+nix develop .#
-cd infrastructure
+remote-install hostname 10.0.42.23
-
-# add the new generated hardware config (and import in hosts configuration.nix)
-cp /tmp/config/etc/nixos/hardware-configuration.nix machines/bakunin/
-
-# check which harddrive we want to install the system on
-lsblk #choose harddrive, in this case /dev/sda
-
-# run nixos-install on that harddrive
-sudo nix --extra-experimental-features flakes --extra-experimental-features nix-command run 'github:nix-community/disko/latest#disko-install' -- --flake .#bakunin --disk main /dev/sda
-
-# this failed with out of memory
-# running again showed: no disk left on device
-# it seems the usb stick i used for flashing is way to small
-# it is only 
-# with a bigger one (more than 8 gig i guess) it should work
-# instead the disko-install tool i try the old method - first partitioning using disko and then installing the system
-# for that i needed to adjust ./machines/modules/disko/btrfs-laptop.nix and set the disk to "/dev/sda"
-
-sudo nix --extra-experimental-features "flakes nix-command" run 'github:nix-community/disko/latest' -- --mode format --flake .#bakunin
-
-# failed with no space left on device.
-# problem is lots of data is written to the local /nix/store which is mounted on tmpfs in ram
-# it seems that a workaround could be modifying the bootable stick to contain a swap partition to extend tmpfs storage
 ```
