Why does Ubuntu 18.04 doesn't create multiple BTRFS subvolumes anymore during installation by default?

Actually, yes, @home is mounted after root, it's not a subvolume of /
both / and /home are subvolumes that exist on the same device... (you
can think of it as a traditional 2 partition scheme.  Mechanically, for
fstab, it works the same way.  The only difference is the use of
subvol=@ and subvol=@home options instead of device partition numbers.

That being said, I would think fixing the dependencies of systemd units
so that whatever it is waits until file systems are mounted would be a
better approach.
