Enable Hibernate on BTRFS and LUKS using a Swap file

This is a setup on how to enable Hibernate on an LUKS encrypted Volume using a swap file. Why? Because if you are using an encrypted Swap partition, you'll have to enter your decryption password twice... and that's lame.

Tested on Manjaro.

1. Create Swap subvolume

btrfs subvolume create /swap

check: btrfs subvolume list /
