It's for very good reason btrfs is described as:
Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET FINALIZED. You should say N here unless you are interested in testing Btrfs with non-critical data.
Btrfs is approximately 5 years old now, by my estimate. How long does it usually take for a new file system to reach the point at which most users in most scenarios don't run into serious problems? Note that EXT3 to EXT4, for example, isn't a good comparison because it's essentially a revision of an existing design rather than a new one. Of course, Btrfs is also more complex than anything that comes to mind other than Zfs and perhaps certain network-based file systems that have their own on-disk formats. The question is: how is Btrfs progressing relative to what one would expect in this time-frame?
