# Turn a Cloud at Cost CentOS-7-64bit server into NixOS

1. Configure the system (`$systemname`) you'd like to install (see Configuration below).
2. Create new server instance (either Custom or cloudpro) using "CentOS-7-64bit".
   Note the servername (something like c731445864-cloudpro-388922936).
3. `cac_login=xxx cac_key=yyy ./infest-cac-CentOS-7-64bit.sh servername:$servername $systename`
4. Enjoy. (`ssh root@$systename`)

# Configuration

Configure your system in modules/$systemname
See modules/cd/default.nix as an example.

Notice that modules/$systemname/networking will be autogenerated (but not committed).

secrets/$systemname/nix/foo can be accessed as `<secrets/foo>` from within the configuration.

You might want `secrets/$systemname/rsync/etc/tinc/retiolum/rsa_key.priv`.

You might want `secrets/$systemname/nix/hashedPasswords.nix`, which looks like

```nix
_: { users.extraUsers.root.hashedPassword = "XXX"; }
```

`XXX` can be generated with e.g.

```
mkpasswd -m sha-512 -S $(openssl rand -base64 16 | tr -d '+=' | head -c 16)
```
