I want to install an Ubuntu Server 11.10 with a BTRFS filesystem (in a RAID1 way).

The problem is that I can't see the option in the installer to make more subvolumes. The installer creates two by default: @ and @home, and I want to separate also @var @tmp...

Is there any option to do this? Maybe with the shell... but I think the installer doesn't understand the subvolumes feature of btrfs, so you can't mount each partition in each subvolume...

Any idea? :)
