Be aware that some distribution installers may implicitly create
subvolumes. For example the Debian installer creates a subvolume
"@rootfs" for the root filesystem, but Debian's os-prober looks only
into the top-level subvolume (or the first mounted subvolume) when
probing GNU/Linux systems.
You can check subvolumes in an unmounted btrfs filesystem with:
# mount /dev/sda2 /mnt
# btrfs subvolume list /mnt
# btrfs subvolume get-default /mnt
# umount /mnt
