Ubuntu cloud-init autoinstall

Create an Ubuntu 20.04 LTS autoinstall USB

This only works with UEFI boot.

  1. Get a USB key and format it with a GPT partition table. Using gptfdisk something like this should do it: 
    sgdisk -og /dev/sdX
sgdisk -n 0:0:0 -t 0:ef00 /dev/sdX

Create a FAT32 partition, mount it and extract the ISO image to that location

/etc/acpi/power.sh and /etc/rc.local For good laptop powersaving. I reccommend it!

if on_ac_power; then
echo "Power mode"
echo 0 > /proc/sys/vm/laptop_mode
echo 10 > /proc/sys/vm/dirty_ratio
echo 5 > /proc/sys/vm/dirty_background_ratio
