F13 with btrfs inside lvm won't boot

[Bertrand Juglas]

I'm using a F13 Beta RC4 with a root filesystem formated as btrfs
inside a LVM and i have not seen any problems yet.
I've just use the manual partitionning because my partitions and LVM
was already created my a previous install.
Hoping it will help you to know BTRFS already works well inside LVM on
some F13 installs.
