F23 sounds about right to me.  I am very much a fan of BTRFS and 
currently use it on all of my systems with few problems but I think that 
F22 is a bit early to make it the default.

However, I do believe that there a couple of things that need to happen 
to make thjings easier/better:

1.  The Fedora developers/maintainers need to take BTRFS more seriously 
and address btrfs related problems seriously and quickly. Yes, I know 
that BTRFS swap draining is a little bit difficult to deal with when you 
are up to you rear end in alligators but, a little more attension please.

2.  Currently anaconda supports supports installation of /boot on BTRFS 
either as a simple directory on a BTRFS volume (yes, I don't understand 
why someone would do this but ...), as a simple directory on a rootfs 
("/") subvolume, or as a spepate subvolume.  Grub2.02 also supports this 
and grubby will support if "real soon now" when pjones can get enough 
time to examine and integrate my grubby patches adding BTRFS support.

3.  About the only thing that I would like to see changed is to move the 
drop-down menu which selects the filesystem type from the "custom" to 
the previous (disks?) panel.  This would allow a user to select BTRFS 
and then let anaconda do its automagic allocation. Yes, I now it is not 
that hard to select custom, then select BTRFS and then click on the auto 

Anyway, we are getting close.
