timeshift-autosnap-apt

In this guide I will walk you through the installation procedure to get a Pop!_OS 20.04 system with a luks-encrypted partition which contains a LVM with a logical volume for the root filesystem that is formatted with btrfs and contains a subvolume @ for / and a subvolume @home for /home. I will show how to optimize the btrfs mount options and how to setup an encrypted swapfile. 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. The recovery system of Pop!_OS is also installed to the disk and accessible via the systemd bootloader.
