Installing profiles

The easiest way is to use the provided network.nix and configuration.nix with [nixops](https://nixos.org/nixops/manual/).
Once you've set up nixops first run `./generate_secrets.sh` then continue with the deployment using nixops.
The easiest way is to run `nix-shell env.nix` and then create a [nixops](https://nixos.org/nixops/manual/) deployment with the provided network.nix.
Fix the FIXMEs in configuration.nix and deploy with nixops in nix-shell.
At the moment this relies on using the unstable nixpkgs channel.
The "all" profile requires 15 GB of disk space and 2GB of memory.
Tutorial: install a nix-bitcoin node on Debian 9 Stretch in a VirtualBox

Currently there is an upstream bug in the nixops package which results in an error during `nixops create`. That is why we have to build nixops from source until a binary with the bug-fix is released.
Build Nixops from source
```
git clone https://github.com/NixOS/nixops
cd ~/nixops
nix-build release.nix -A build.x86_64-linux
cd
```
This should output a last line like `/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/`. This is the directory Nixops is installed in. Note it for later.

Generate Secrets
Setup environment
```
./generate_secrets.sh
nix-shell env.nix
```
Create Nixops
Create nixops deployment in nix-shell
```
nixops create network.nix network-vbox.nix -d bitcoin-node

Replace `nixops` with the path to the nixops you built from source. For example: `/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/bin/nixops`. Alternatively you can change your path, i.e. `export PATH=/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/bin/:$PATH` so you can just type nixops.
Adjust configuration
Open configuration.nix and remove FIXMEs.
No custom boot options or hardware configuration is needed for a VM install.
Deploy Nixops
Deploy Nixops in nex-shell
```
nixops deploy -d bitcoin-node
```
If you haven't changed your nixops path, replace `nixops` with the path to the nixops you built from source. For example: `/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/bin/nixops`
This will now create a nix-bitcoin node in a VirtualBox on your computer.
Nixops automatically creates a ssh key and adds it to your computer.
Access `bitcoin-node` through ssh
Access `bitcoin-node` through ssh in nix-shell.
```
nixops ssh operator@bitcoin-node

If you haven't changed your nixops path, replace `nixops` with the path to the nixops you built from source. For example: `/nix/store/wa6nk3aqxjb2mgl9pkwrnawqnh9z1b9d-nixops-1.6.1pre0_abcdef/bin/nixops`
