F13 with btrfs inside lvm won't boot

[Michael Cronenworth]

I installed F13 beta RC4 with all the defaults, except I installed on 
two Intel SSDs (40gig G2 drives) in a Linux software RAID1 
configuration. I left anaconda to install /boot to ext4 and / to an LVM 
with ext4 and a swap area inside of it. The benchmark results from 
palimpset show me maxing out my SATA 2 links. :)

I rebooted into a F13 beta RC4 live USB drive and ran "btrfs-convert 
/dev/mapper/vg_foo-LogVol00" and it converted successfully. I updated my 
/etc/fstab from "ext4" to "btrfs" as the root file system. Upon 
rebooting I was met with a failure of setting the hostname (odd) and 
then iptables complained of missing library files and 90% of the default 
services failed to start. The init failed to kick off TTYs and the X 
server so I was not given a login. I can hit CTRL+ALT+DEL and reboot, 
however.

I entered into the live image again and set back fstab to "ext4" and 
rebooted. I was presented with a rescue boot prompt and gave it the root 
password. From there I changed my fstab to "btrfs" and typed "reboot" 
and Fedora continued to successfully boot (without physically rebooting) 
and I am typing this message from the install while the rootfs is btrfs. 
If I were to reboot right now, Fedora would not come back up and would 
result in the same service start-up failures. I would have to repeat my 
hack of setting fstab back to "ext4".

What am I missing from having a working btrfs system? Or is this a bug?

Thanks,
Michael
