It is possible to reuse btrfs subvolumes for mount points other than root. Root requires a new subvolume.

I first bootup in rescue mode and delete the old root subvolume and then reboot to do the install.  I probably need to figure out out a pre-install script which will do that.

No need to delete the previous subvolume unless you want to delete the installation contained on it.

Reuse is inconsistent with delete, but yes you can't reuse an existing subvolume for rootfs for a new install.
