soooo apparently ubuntu server used to install to separate btrfs subvolumes on install, but now in 24.04 it just installs to the btrfs root. anyway i've been wanting to migrate to a separate subvolume install for a while now. thanks to this post for steering me in the right direction https://www.kubuntuforums.net/forum/general/miscellaneous/btrfs/680895-converting-a-root-btrfs-install-to-a-subvolume-install-in-4-easy-steps
