# AUR Package Manager
This project uses some packages from the Arch Linux AUR repos. As such, we are going to setup a package manager for those packages. Pacman doesn't support the AUR repos natively and this is the most accessible approach for installing AUR packages.
The commands below will setup the ```yay``` AUR package manager.
``` sh
pacman -S --needed base-devel go
useradd yay -s /usr/bin/nologin
mkdir /home/yay
chown yay: -R /home/yay
git clone https://aur.archlinux.org/yay.git /opt/yay
chown yay: -R /opt/yay/
cd /opt/yay
cat > /etc/sudoers.d/yay <<EOF
yay ALL=(ALL) NOPASSWD: ALL
EOF
chmod 600 /etc/sudoers.d/yay
sudo -sHu yay makepkg -si
cat >> ~/.bashrc <<EOF
alias yay="/usr/bin/sudo -sHu yay /usr/bin/yay"
EOF
source ~/.bashrc
```

# Base Firmware Setup
The ```PiFrame``` uses Arch Linux at its core. This document will outline a way to setup a micro sd card with Arch Linux.
The ```PiFrame``` uses Ubuntu Linux at its core.
# Please Note
There are a lot of documents online on how to flash Ubuntu to an sd card for the Raspberry Pi 4.
We assume you're going to use the Raspberry Pi itself for setting up an Arch Linux environment. In order to do this properly and safely, you'll need 2 micro sd cards and a USB to micro sd card adapter.
# Setup an Ubuntu SD Card
The first step is to setup a basic Ubuntu boot environment for the Raspberry Pi, we will use this to boot strap (initialize) the Arch Linux micro sd card. This Ubuntu micro sd card can also be used to recover a broken Arch Linux system if necessary.
1. Download Ubuntu from their main [download site](https://ubuntu.com/download/raspberry-pi/thank-you?version=20.04&architecture=arm64+raspi) and flash it to the sd card. There are a lot of guides on how to do this online.
1. Boot the Ubuntu installation
1. Check the ip address with ```ip addr`` and ssh into the environment if desired. This step can be skipped if you have a keyboard/monitor setup.
1. Login to the Ubuntu envrionment
1. Open a terminal
1. Run ```sudo -sHu root``` to elevate your privileges
# Prep / install arch linux on micro sd card
## Inspiration and Further Reading
- [https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4#installation](https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-4#installation)
- [https://github.com/phortx/Raspberry-Pi-Setup-Guide](https://github.com/phortx/Raspberry-Pi-Setup-Guide)
## Arch Linux Disk Setup
Run the following commands to prep the Arch Linux micro sd card. Please note the device nodes like ```/dev/sda``` may be different depending on the usb adapter used.
``` sh
parted /dev/sda
mklabel msdos
mkpart
p
[enter]
1
100M
mkpart
p
[enter]
100M
-1
set 1 boot on
set 1 lba on
q
mkfs.fat /dev/sda1
mkfs.btrfs /dev/sda2
```
## Arch Linux Bootstrap
Run the following commands to bootstrap (initialize) a fundamental Arch Linux installation.
``` sh
mkdir /mnt/arch
mount -o nodiratime,noatime,compress /dev/sda2 /mnt/arch
mkdir /mnt/arch/boot
mount /dev/sda1 /mnt/arch/boot
cd /mnt/arch
wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-4-latest.tar.gz
tar -xpf ArchLinuxARM-rpi-4-latest.tar.gz
rm ArchLinuxARM-rpi-4-latest.tar.gz
```
## Tweak Bootstrapped System
The following commands will tweak the base Arch Linux distro to facilitate the needs of a photo frame as well as tune some of the debugging that's present in the default setup.
``` sh
cat > /mnt/arch/boot/config.txt <<EOF
# KmN: Borrowed some stuff from majaro
# See /boot/overlays/README for all available options
gpu_mem=512
dtoverlay=miniuart-bt
initramfs initramfs-linux.img followkernel
disable_overscan=1
#enable vc4
dtoverlay=vc4-fkms-v3d
max_framebuffers=1
# Make sure hdmi low power mode is set for when the feature is implemented on the Pi4
hdmi_blanking=1
# you may need to add hdmi settings specific to your lcd display panel
# for example, the below settings are for a 2560x1600 50Hz panel
# see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md
# for additional details
#hdmi_cvt=2560 1600 50 5 0 0 1
#hdmi_group=2
#hdmi_mode=88
EOF
nano -w /mnt/arch/boot/cmdline.txt
root=/dev/mmcblk0p2 rootflags=nodiratime,noatime,compress rw rootwait
remove kgdboc=ttyAMA0,115200
parted /dev/sda
set 1 boot on
set 1 lba on
set 2 lba on
q
```
## Boot Arch Linux
That should do it for the bootstrapping process. You can now shutdown the Ubuntu environment via ```systemctl poweroff```, swap the micro sd cards and boot into the Arch Linux environment.
You should not need the Ubuntu micro sd card at this point unless you need to recover or fix a broken Arch Linux installation.
**Please Note: You'll want the most recent LTS 64bit server version of Ubuntu for your PiFrame**

The below commands will setup ```cockpit``` so you can manage your PiFrame from a web browser. This is wholly optional but can be useful when ssh/serial terminal access aren't available.
If you don't want the admin UI you still should install ```NetworkManager``` and ```firewalld``` as the rest of the documentation assumes these are installed.

# cron/Scheduler
The below commands will setup a cron daemon (scheduler) for running things like backups, statistic gathering and more via a schedule. While technically not required, we *strongly* recommend using cron for backups so you get the output via e-mail (or similar). This is also required if you want to monitor resource utilization via ```munin```.
## Important Notes
* This assumes you have setup ```msmtp``` for email notifications

# Slideshow
The below commands will setup ```feh``` as a slideshow on your display.
The below commands will setup ```fim``` as a slideshow on your display.
## Important Notes
* ```feh``` will crash if there are no photos for it to use as a slideshow
* You will likely want to tweak the ```feh``` command invocation below. These are great settings as a starting point but you'll probably want to make adjustments for your use case.
* This setup uses ```incron``` to restart ```feh``` when photos are deleted from the pictures folder. Without this piece ```feh``` will crash if a picture is removed from the pictures directory prior to ```feh``` rescaning the pictures directory.
* We default to ```DejaVuSansMono``` as the font for display of EXIF data and filename. This is an open font and looks great on most displays. Any ```fontconfig``` font can be used in its place. Adjust according to your preferences.
* ```fim``` will crash if there are no photos for it to use as a slideshow
* You will likely want to tweak the ```fim``` command invocation below. These are great settings as a starting point but you'll probably want to make adjustments for your use case.
* This setup uses ```incron``` to restart ```fim``` when photos are deleted from the pictures folder. Without this piece ```fim``` will crash if a picture is removed from the pictures directory prior to ```fim``` rescaning the pictures directory.
## Setup
``` sh
pacman -S feh imagemagick ttf-dejavu
# reload 86400 is to refresh the list of images daily -- tune for preferred number of seconds
# slideshow-delay is number of seconds (as a float) between images ; tune accordingly
useradd -s /usr/bin/nologin -m feh
chmod a+rx /tank/pictures
pacman -S acl
setfacl -m "u:feh:rX" /tank/pictures
setfacl -dm "u:feh:rX" /tank/pictures
pacman -S incron
