Btrfs hibernation script

mkdir -p ~/.gc && cd ~/.gc && git clone --quiet https://github.com/pietryszak/fedora-hibernation.git && cd fedora-hibernation && chmod +x hibernation.sh after-restart.sh

Before run script adjust your swap size

sudo sed -i 's/sudo fallocate --length 96GiB /swap/swapfile/sudo fallocate --length YOUR_SWAP_FILE_GiB /swap/swapfile/g' ~/.gc/fedora-hibernation/hibernation.sh && ./hibernation.sh

Redhat swap size recommendations

RAM	Swap size (With Hibernation)
⩽ 2 GB	3 times the amount of RAM
> 2 GB – 8 GB	2 times the amount of RAM
> 8 GB – 64 GB	1.5 times the amount of RAM
> 64 GB	Hibernation not recommended

After automatic restart of PC after first script use second script (script restart PC once again)

sh -c ~/.gc/fedora-hibernation/after-restart.sh
