# disko + nixos-anywhere
This is an example repo for nixos-anywhere and disko.
## Build installer ISO with SSH
```shell
nix-build '<nixpkgs/nixos>' -A config.system.build.isoImage -I nixos-config=iso.nix
ls result/iso/
```
## Hardware Configuration
Boot the target machine into NixOS live ISO. Then execute the following, ideally while connected via SSH:
```shell
nixos-generate-config --no-filesystems --root /mnt
cat /mnt/etc/nixos/hardware-configuration.nix
```
Save the output to a new file in [./hardware-configs/](./hardware-configs/). In [./flake.nix](./flake.nix) replace `./hardware-configs/yodaHP.nix` with it.
Note: The hardware configuration should not contain any `fileSystems.<name>` options as these are generated based on your disko configuration.
## Installation
To run the interactive vm test run:
```shell
nix --extra-experimental-features nix-command --extra-experimental-features flakes \
run github:numtide/nixos-anywhere -- -f '.#mysystem' --vm-test
```
To install on remote target machine:
```shell
# GNOME Boxes
#nix --extra-experimental-features nix-command --extra-experimental-features flakes \
# run github:numtide/nixos-anywhere -- --flake '.#mysystem' -p 2222 root@localhost
# yodaHP
nix --extra-experimental-features nix-command --extra-experimental-features flakes \
run github:numtide/nixos-anywhere -- --flake '.#mysystem' -p 22 root@192.168.178.105
```
## Updating dependencies
Recreate the lock file (i.e. update all inputs) and commit the new lock file:
```shell
nix --extra-experimental-features nix-command --extra-experimental-features flakes \
flake update --commit-lock-file
```
