Hi Ted

The btrfs filesystem effort is an attempt to create a filesystem that 
will leapfrog the ZFS feature set, but it will probably take longer to 
reach production ready status than ext4.

Since you mention btrfs here and since I've read this earlier too, do
you know if btrfs will be the default Linux file system in the future,
like extX has been?

What happens in the future, who can say?  At some point the ext2/3/4
filesystem, which is based fundamentally on a BSD Fast Filesystem
design base, may get displaced by a filesystem which uses some very
different design as a starting point, when the advantages of starting
with that different design outweighs the advantages of backwards
compatibility and broad base of support which is enjoyed by ext2/3/4.

Thanks. That sums up the trade-off pretty clearly.
