Even though it is not grub-mkrelpath's fault that the default subvolume is ignored, the resulting grub-conf includes the subvolume path as the root prefix of the kernel path and this is wrong.


btrfs default submodule: /__active

wrong: linux   /__active/boot/vmlinuz-linux root=UUID=... rw rootflags=subvol=__active

correct: linux   /boot/vmlinuz-linux root=UUID=... rw rootflags=subvol=__active

The rootflags may be superfluous but the linux path should be fixed or it won't boot. The result is grub searching for the kernel in the effetive path: /__active/__active/boot/vmlinuz-linux

Using the real root is a concious decision and it is in line with GRUB always using absolute path and not trying to follow any artificial "defaults". grub-mkrelpath bridges this difference by adding necessarry prefix.

It doesn't recognize btrfs default subvolume. (which is permanently pointed to by the command "btrfs subvolume set-default #subvolid")
Instead, it sees the root (thus, subvolume 0)

But it is not beta1, it is 2.02~beta2.
