The store's sort no longer lives on the kernel stack (heapsort, see the parent commit's gate), and the release is now 6.19.3-cubelinux0.6 instead of CUBELinux.0.6 — depmod/mkinitramfs reject a version whose first character is not numeric, so the literal name cannot be uname -r. The box's own kernel uses the same shape (6.19.3-cube+); this is the same concession.
