my tricks with btrfs (no partitions):

dd if=/dev/zero of=/dev/sda bs=4096

mkfs.btrfs -L dev_sda /dev/sda
mount /dev/sda /mnt

cd /mnt
btrfs subvolume create __active
btrfs subvolume create __active/rootvol
btrfs subvolume create __active/usr
btrfs subvolume create __active/home
btrfs subvolume create __active/var
btrfs subvolume create __snapshots

cd /
umount /mnt
mount -o subvol=__active/rootvol /dev/sda /mnt
mkdir /mnt/{usr,home,var}
mount -o subvol=__active/usr /dev/sda /mnt/usr
mount -o subvol=__active/home /dev/sda /mnt/home
mount -o subvol=__active/var /dev/sda /mnt/var

# /etc/fstab
UUID=ID / btrfs rw,relative,space_cache,subvol=__active/rootvol 0 0
