raspberry pi

In the following I will go through my post installation steps, i.e. which settings I choose and which apps and containers I install and use on my Raspberry Pi 4 (4 GB)

In this guide I will walk you through the installation procedure to get an Ubuntu 20.10 system with a luks-encrypted partition for the root filesystem (excluding /boot) formatted with btrfs that contains a subvolume @ for / and a subvolume @home for /home running on a Raspberry Pi 4. The system is installed to an external bootable USB drive so no SD card is required. I will show how to optimize the btrfs mount options and how to get a headless server, i.e. remotely unlock the luks partition using Dropbear which enables one to use SSH to decrypt the luks-encrypted partitions after a reboot. This layout enables one to use Timeshift and timeshift-autosnap-apt which will regularly take snapshots of the system and particularly on any apt operation.
