Saturn is the NAS server.
The configuration of this machine is splitted in two steps:
- Installation and first setup are done using the script into the
provisionersfolder, which is intended to run only once. After the installation the machine has root openssh access available. - Following configurations are deployed with deploy-rs, from the current flake.
To reinstall the system from scratch, prepare a USB key with the NixOS minimal installer. Boot the system from the USB key in UEFI mode (there will be two entries in the boot options, select the UEFI entry).
Then run the provisioning script from a remote machine:
./provisioners/saturn/provision.sh MACHINE_IP
Note that the script will configure a static IP for the machine which is 192.168.8.102. Remember to change it if needed. Also remember that the private key of the system always change on new installations (this in turn requires secrets to be encrypted again).
Then install nixos within the machine terminal:
sudo nixos-install
After installation run once the rebuild command on the machine:
sudo nixos-rebuild switch -I config=/etc/nixos/configuration.nix
After the first installation, deploy a new configuration using this flake and deploy-rs:
deploy --hostname MACHINE_IP/HOSTNAME .#saturn
Backups are executed daily with:
