---------------------------------------------
In this video we'll install Pop!_OS 21.04 with the following structure:
a BTRFS-LVM-inside-LUKS partition for the root filesystem
the BTRFS logical volume contains a subvolume `@` to mount `/` and a subvolume `@home` to mount `/home`. Note that the Pop!_OS installer does not create subvolumes on BTRFS besides the top-level one, so this requires these manual steps.
Timeshift is set up to automatically create snapshots of the system
timeshift-autosnap-apt is set up to automatically take snapshots of your system after any APT command and also to rsync your EFI partition into the snapshots for flexible restoring options
