HI everyone,

I tried to install btrfs on my root filesystem (/), this is what I did :

install debian with :
/boot (ext2) (for grub),
/ (ext3),
swap,
grub on MBR.

compile the 2.6.31-rc4 from kernel.org with btrfs support
test the new kernel by rebooting (worked fine)
install btrfs-tools from debian sid repository (0.19-2)

boot on a ubuntu 9.04 live cd
