Not Booting on Debian 13

[AhTeeGuu3u]

Hello,
thank you starting this project!
Testing with Debian 13, systemd, grub, btrfs root, non-efi, gnome-shell....

It all seems fine, but i think the root_switch does not happen.

your script works fine, but

• on btrfs it does not mount the correct subvolume to /oot.
  If i do this, it works: btrfs subvolume set-default @rootfs
• if the real root has compression enabled, i think the space calculation is off
