This machine is intended to host web applications. Initially [Lemmy](https://join-lemmy.org/), but perhaps more down the line. The initial PR only deals with setting up the machine and required infra like DNS, not setting up Lemmy itself which will be a follow-up.

## Install/Fix system from Hetzner recovery mode
|
|
|
|
1. Copy your ssh key to the recovery system so that the kexec image can re-use it.
|
|
|
|
```console
|
|
yourmachine> ssh-copy-id root@build0X.nix-community.org
|
|
```
|
|
|
|
2. Download and boot into kexec-image:
|
|
|
|
```console
|
|
$ curl -L https://github.com/nix-community/nixos-images/releases/download/nixos-unstable/nixos-kexec-installer-x86_64-linux.tar.gz | tar -xzf- -C /root
|
|
$ /root/kexec/run
|
|
```
|
|
|
|
### Debug VM
|
|
|
|
You can start a vm from the rescue system in order to debug the boot:
|
|
|
|
```console
|
|
$ nix-shell -p qemu_kvm --run 'qemu-kvm -m 10G -hda /dev/sda -hdb /dev/sdb -curses -cpu host -enable-kvm'
|
|
```
