## Goal
The goal is to never setup and configure a system manual again or to care about loosing passwords and important data. Instead the whole process **SHOULD** be automatized.

## Description
This repository contains scripts to set up an working client system, maintain it and to save all important and configuration data on an USB stick. The data is stored encrypted with [EncFS](https://en.wikipedia.org/wiki/EncFS).
It's adapted to the needs of Kevin Veen-Birkenbach. Feel free to modularize it and to adapt it to your needs.

<sub>*Core System* changes the wallpaper every day to the [Astronomy Picture of the Day](https://apod.nasa.gov/apod/). This wallpaper is from the 2019-10-07 and shows Jupiter with the shadow of his moon Io. </sub>

## Core System Norm
This software and compatible software **MUST** adapt to the ["Core System Norm"](./CORE_SYSTEM_NORM.md).


## Requirements
This script is optimized for a [Manjaro Linux](https://manjaro.org). It's recommended to encrypt the hard drive with [LUKS](https://en.wikipedia.org/wiki/Linux_Unified_Key_Setup) if the computer isn't shared.

## System
### Desktop
The System allows to use a [GNOME desktop](https://www.gnome.org/?) or a [Xfce](https://www.xfce.org/) desktop.
Depending on the desktop environment you have different functionalities.
#### GNOME
##### Key Bindings
The following *Core System* specific key bindings exist:

### User Data
Right now the software expects that the *Core System Owner* has on all systems the same username. By executing the *import script* it automatic backups the application configuration data, ssh keys and other important data which is saved in well defined configuration files and folders.

### Functions

# Raspberry Pi sdc tools
This repository contains some shell scripts to install Arch Linux for the Raspberry Pi on a SD-Card and to backup a SD-Card.
## Todo

- Implement ssh configuration
- Implement wifi automation

## Setup
### SD-Card
#### Guided
To install a Linux distribution manually on a SD card type in:

```bash
  bash ./sd_setup.sh
```
#### Piped
To pase the configuration to the program use this syntax:
```bash
(
  echo "$USER"              # | The username
  echo "mmcblk1"            # | The device
  echo "3"                  # | The raspberry pi number
  echo "arch"           # | The operation system
  echo "n"                  # | Force image download
  echo "n"                  # | Transfer image
  #echo "n"                 # ├── Overwrite device before copying
  echo "test12345"          # | The user password
  echo "test12345"          # | The root password
  echo "example-host"       # | The hostname
  echo "y"                  # | Setup Wifi on target system
)| sudo bash ./sd_setup.sh
```

### System
#### Arch
```bash
  pacman-key --init
  pacman-key --populate archlinuxarm
  install -m640 /etc/netctl/examples/wireless-wpa domo-de-kosmopolitoj-wpa
