LinuxBSDos.com posted a guide about installing Linux Mint 11 on a btrfs file system

Like Ubuntu 11.04 on which it is based, Linux Mint 11 has support for btrfs, a modern journaling file system with features that are not available on the default file system on Linux. For example, with btrfs, you can:

Writable snapshots
Subvolumes (separate internal filesystem roots)
Object level mirroring and striping
Integrated multiple device support, with several raid algorithms
Efficient incremental backup and FS mirroring
While it is still in development and not yet certified for use in production, now presents a good opportunity to try to get familiar with it, in preparation for when it will become the default, which it will soon. It is already the default on MeeGo.

This tutorial presents the simple steps involved in installing Linux Mint 11 on a btrfs file system.
