## Baseline setup
Replace `$TAG` with whatever version is being built, e.g. `v1.2.1`.
Replace `$TAG` with whatever version is being built, e.g. `v2.0.0`.
1. Flash your SD card (assuming OS X):
1. Get [Ubuntu MATE 16.04](https://ubuntu-mate.org/raspberry-pi/) and decompress into an `.img` file
1. `$ diskutil list` to check correct device
1. `$ diskutil unmountDisk /dev/disk2` to prepare it for imaging
1. `$ sudo dd bs=1m if=ubuntu-mate-16.04-desktop-armhf-raspberry-pi.img of=/dev/rdisk2` (will take a while)
1. Boot your Raspberry Pi using the SD card (the setup should be done on a Pi 3, but the resulting image will work on Pi 2 as well)
1. Answer basic questions (timezone, keyboard layout, default user, etc)
1. Set hostname to `chilipie-kiosk`
1. Set username/password to `pi:raspberry` (or whatever you want)
1. Log in automatically after boot
1. At this point you can already SSH onto the Pi and do the rest of the setup remotely
1. `$ sudo visudo` and add `pi ALL=(ALL) NOPASSWD: ALL` to allow sudo without password prompt
1. Disable MATE's default desktop with `$ sudo graphical disable` (though later nodm will boot directly to matchbox anyway)
1. Clean up MATE's desktop cruft with `$ rm -rf ~/*`
1. Remove some packages we don't need: `$ sudo apt-get purge -y $(dpkg --get-selections 'sonic*' 'thunderbird*' 'libreoffice*' 'minecraft*' 'scratch*' 'shotwell*' 'simple-scan*' 'hexchat*' 'pidgin*' 'transmission*' 'youtube-dl*' 'atril*' 'idle*' 'brasero*' 'omxplayer*' 'rhythmbox*' 'supercollider*' 'vlc*' | cut -f 1 | tr '\n' ' ')`
1. Install some packages we'll need: `$ sudo apt-get update && sudo apt-get install -y vim nodm matchbox-window-manager unclutter mailutils nitrogen jq`
* When mailutils prompts about its setup, "local only" is fine (we install mailutils so that you can check `mail` for cronjob output)
1. For the time being, the Chromium from Ubuntu repo's [keeps segfaulting](https://ubuntu-mate.community/t/chromium-crashes-when-starting-segfaults/4578/27), so use the [alternate installation method](https://ubuntu-mate.community/t/tutorial-install-working-chromium-50/6762) instead of installing the `chromium-browser` package directly
1. Remove unnecessary packages with `$ sudo apt-get autoremove -y && sudo apt-get clean`
1. Make sure [automatic software updates are disabled](http://ask.xmodulo.com/disable-automatic-updates-ubuntu.html), in `/etc/apt/apt.conf.d/10periodic`:
APT::Periodic::Unattended-Upgrade "0";
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Download-Upgradeable-Packages "0";
APT::Periodic::AutocleanInterval "0";
1. In `/etc/default/nodm`, set:
NODM_ENABLED=true
NODM_USER=pi
NODM_FIRST_VT=8
1. In `/usr/share/plymouth/themes/ubuntu-mate-text/ubuntu-mate-text.plymouth`, set:
[ubuntu-text]
title=chilipie-kiosk
black=0x000000
1. In `/usr/share/plymouth/themes/ubuntu-mate-logo/ubuntu-mate-logo.script`, set:
Window.SetBackgroundTopColor (0, 0, 0);
Window.SetBackgroundBottomColor (0, 0, 0);
1. Replace the Plymouth theme logos with `$ cd /usr/share/plymouth/themes/ubuntu-mate-logo && sudo rm ubuntu-mate-logo{,16}.png && sudo ln -s /home/pi/background.png ubuntu-mate-logo.png && sudo ln -s /home/pi/background.png ubuntu-mate-logo16.png`
1. Check that the version in `.chilipie-kiosk-version` matches `$TAG`, and it's on GitHub
1. Get default scripts with `$ wget "https://github.com/futurice/chilipie-kiosk/archive/master.zip" && unzip master.zip && cp -v $(find chilipie-kiosk-master/home/ -type f) . && rm -rf chilipie-kiosk-master/ master.zip`
1. Put in the example crontab with `$ crontab -e`:
# m h dom mon dow command
# 0 7 * * 1-5 ~/display-on.sh # turn display on weekdays at 7 AM
# 0 19 * * 1-5 ~/display-off.sh # turn display off weekdays at 7 PM
1. Disable overscan for HDMI output (as this is rarely needed on modern displays) by uncommenting `disable_overscan=1` in `/boot/config.txt`
1. Set up WiFi (for Raspberry Pi 3 only):
1. Check the interface name with `$ ifconfig`, e.g. `wlan0`
1. Append to `/etc/network/interfaces`:
```
# Internal WiFi adapter
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
```
1. In `/etc/wpa_supplicant/wpa_supplicant.conf`:
```
network={
# Your network name goes here:
ssid="networkname"
# EITHER: uncomment this for a password-protected WLAN:
#psk="secretpassword"
# OR: uncomment this for an unprotected WLAN:
#key_mgmt=NONE
}
```
1. Symlink the file, for convenience: `$ ln -s /etc/wpa_supplicant/wpa_supplicant.conf wlan.conf`
1. Disable SSH access (because the default credentials aren't very secure): `$ sudo systemctl disable ssh.service`
1. Reboot (should land you in Chromium)
1. Tell Chromium "Don't ask again" about being the default browser
1. Configure Chromium to start from "where you left off", and navigate to https://github.com/futurice/chilipie-kiosk/blob/$TAG/first-boot.md
1. Unpower the Pi
1. Check that the version in `.chilipie-kiosk-version` matches `$TAG`, and it's on GitHub
1. Get Raspbian Lite (`2018-06-27-raspbian-stretch-lite.zip`)
1. Flash it onto an SD card (use [Etcher](https://etcher.io) or `dd`)
1. Re-mount the card
1. Update the file `/Volumes/boot/cmdline.txt` on the card:
```diff
-dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=4d3ee428-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet init=/usr/lib/raspi-config/init_resize.sh
+dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=PARTUUID=4d3ee428-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet
```
1. Boot your Pi from the SD card
1. Run `sudo raspi-config` and:
1. Set localization options
1. Set hostname to `chilipie-kiosk`
1. Join a WiFi (if wired network isn't available for setup)
1. Enable SSH
1. Set automatic CLI login after boot
1. At this point you can already SSH onto the Pi and do the rest of the setup remotely
1. [Resize the root partition](https://elinux.org/RPi_Resize_Flash_Partitions#Manually_resizing_the_SD_card_on_Raspberry_Pi) to make space for additional software
1. `sudo fdisk /dev/mmcblk0`
1. `p`
1. Make note of the "Start" value of the 2nd partition (e.g. `98304`)
1. `d`
1. `2`
1. `n`
1. `p`
1. `2`
1. For "First sector", enter the "Start" value from above (e.g. `98304`)
1. For "Last sector", enter `+3G`
1. If asked if you want to remove the existing "ext4" signature, say `y`
1. `w`
1. `sudo shutdown -r now`
1. `sudo resize2fs /dev/mmcblk0p2`
1. `df -h`
1. Install some packages we'll need: `sudo apt-get update && sudo apt-get install -y vim matchbox-window-manager unclutter mailutils nitrogen jq chromium-browser xserver-xorg xinit rpd-plym-splash`
- If `nodm` prompts whether it should be enabled by default, say "yes"
- TODO TODO TODO: nodm NOT NEEDED ANYMORE?
- If mailutils prompts about its setup, "local only" is fine (we install mailutils so that you can check `mail` for cronjob output)
1. Disable overscan (as it's rarely needed on modern displays) in `/boot/config.txt` with:
```diff
-#disable_overscan=1
+disable_overscan=1
```
1. Get default scripts with `wget "https://github.com/futurice/chilipie-kiosk/archive/master.zip" && unzip master.zip && cp -v $(find chilipie-kiosk-master/home/ -type f) . && rm -rf chilipie-kiosk-master/ master.zip`
1. [Customize Plymouth boot theme](https://scribles.net/customizing-boot-up-screen-on-raspberry-pi/):
1. `sudo cp background.png /usr/share/plymouth/themes/pix/splash.png`
1. In `/boot/config.txt`, append `disable_splash=1`
1. In `/boot/cmdline.txt`:
```diff
-TODO
+dwc_otg.lpm_enable=0 console=serial0,115200 console=tty3 root=PARTUUID=4d3ee428-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash quiet plymouth.ignore-serial-consoles logo.nologo vt.global_cursor_default=0

## Dumping the image
Assuming OS X:
1. `$ diskutil list` to check correct device
1. `$ diskutil unmountDisk /dev/disk2` to prepare it for imaging
1. `$ sudo dd bs=1m count=7680 if=/dev/disk2 of=chilipie-kiosk-$TAG.img` (only dump the relevant first ~8 GB, matching the original `ubuntu-mate` image size; takes around 15 minutes)
1. `$ COPYFILE_DISABLE=1 tar -zcvf chilipie-kiosk-$TAG.img.tar.gz chilipie-kiosk-$TAG.img`
1. `$ openssl sha1 chilipie-kiosk-$TAG.img*` and include hash in release notes
1. `diskutil list` to check correct device
1. `diskutil unmountDisk /dev/disk3` to prepare it for imaging
1. `sudo dd bs=1m count=3500 if=/dev/disk3 of=chilipie-kiosk-$TAG.img` (only dump the relevant first ~4 GB; takes around 15 minutes)
1. `COPYFILE_DISABLE=1 tar -zcvf chilipie-kiosk-$TAG.img.tar.gz chilipie-kiosk-$TAG.img`
1. `openssl sha1 chilipie-kiosk-$TAG.img*` and include hash in release notes
