[sles-beta] Problem with LVM and BTRFS

[etso-srva-linux]

Hi all !

In Beta4 (and also Beta3) I try to install my server with the following disk configuration: LVM with BTRFS for system and no separate partition for /home (so I have /home as a BTRFS subvolume).
This configuration seems good for our case because it's easier to manipulate VG/LV instead of device name or UUID.
I saw during the installation that's YaST has created a partition for /boot (sounds strange because I was thinking that GRUB2 can boot on LV) and another partition for the entire BTRFS volume.
The problem is that /boot/grub2/i386-pc and /boot/grub2/x86_64-efi are BTRFS subvolumes on top of a ext4 filesystem and that don't work! And so the boot is hanging (on the /boot mount and the /boot/grub2/* subvolume too).

So, are BTRFS subvolumes on LVM supported?
And is there a way to boot from LV?

Regards,
