Configuration files for the IoT controller

Configuration of the smart home controller Pi 4

This should probably be an Ansible config, or just done automagically by cloud-init

After writing image

• Copy the system-boot directory content into the system-boot partition mount point

• Configure zswap by appending to /system-boot/cmdline.txt:

  zswap.enabled=1 zswap.compressor=lz4 zswap.max_pool_percent=20 zswap.zpool=z3fold
  

After first boot

• SSH to the new instance

• Extract our files

  sudo tar -C writable | pv | zstd | ssh ubuntu@10.0.0.4 sudo tar -C / --numeric-owner --zstd -x
  

• Allocate swap file:

  sudo fallocate /swapfile --length 2G
  sudo chmod 0600 /swapfile
  sudo mkswap /swapfile
  echo '/swapfile  swap swap  defaults  0 2' | sudo tee -a /etc/fstab
  sudo swapon -a
  

• Enable our services:

  sudo systemctl enable --now dwd_10mins.timer
  sudo systemctl enable --now [e-mail]
  sudo systemctl enable --now home-assistant.service
  sudo systemctl enable --now unifi-controller.service
  sudo systemctl enable --now [e-mail]
