btrfs

I would like to make use of Btrfs' transparent compression on an external drive.

Which tool is best for formatting the drive? Disk Utility or GParted?
How do I activate the compression? During formatting or when I mount the drive? I guess at mount time. I'm using usbmount to automatically mount newly attached devices, because nobody is logged in on the desktop. Would I have to set general default options somewhere in a system configuration file to get Btrfs mounted with compression, or would I specify this via FS_MOUNTOPTIONS in /etc/usbmount/usbmount.conf and how?

Thanks!
