Grin, Josef has taken a few weeks off to look after the newly released 
Josefv3.

We've got the pool of web servers on btrfs at 800 now, and soon I'm sure 
it'll start kicking out some fun bugs.

Once we get the btrfs tier up to 1000, I'll have a second slice of 1000 
machines running 3.14 as well (or whatever the current linus rev is).

Those will be btrfs too, I expect the crash recovery code will get quite 
a bit of testing.
