DIY install debian on Oracle Cloud Infrastructure ( Free Tier ) - ARM64
# should works on any cloud-init enabled hypervisor (openstack.. )
# start from a normal ubuntu 20.04 install as minimal was not available for ARM64
# Since ARM64 machines has higher RAM, Shrinking is desired but not necessary. Instead we will increase tmpfs to 1700MB
# Getting root (if sudo -i doesn't work then set a root password beforehand using 'sudo passwd root'
sudo -i
# make sure we are on the highest kernel, so we can delete all the others ...

# If you need Mac compatible MP4 uncomment the following two lines instead of the ones above. It's usually a step under max quality, but this yields true mp4 files:
