Recover GRUB2 with btrfs subvolumes

Create the mount folders:

$ mkdir -p /mnt
$ mkdir -p /mnt/root
$ mkdir -p /mnt/srv
$ mkdir -p /mnt/tmp
$ mkdir -p /mnt/var/log
$ mkdir -p /mnt/var/tmp
$ mkdir -p /mnt/var/cache
$ mkdir -p /mnt/boot/efi

Mount the btrfs subvolumes:

$ sudo mount -o subvol=@ /dev/nvme0n1p5 /mnt
$ sudo mount -o subvol=@root /dev/nvme0n1p5 /mnt/root
$ sudo mount -o subvol=@srv /dev/nvme0n1p5 /mnt/srv
$ sudo mount -o subvol=@tmp /dev/nvme0n1p5 /mnt/tmp
$ sudo mount -o subvol=@varlog /dev/nvme0n1p5 /mnt/var/log
$ sudo mount -o subvol=@varcache /dev/nvme0n1p5 /mnt/var/cache
$ sudo mount -o subvol=@vartmp /dev/nvme0n1p5 /mnt/var/tmp

Mount the EFI partition:

$ sudo mount /dev/nvme0n1p1 /mnt/boot/efi
