Description of problem:
In custom partitioning of the hard drive, a /boot partition was listed for creation, formatted as btrfs.  Anaconda warned that a /boot partition formatted as btrfs isn't bootable, and asked me to choose a different format.  However, grub2, which is now installed by default in Fedora 16, supports booting from btrfs partitions.

Version-Release number of selected component (if applicable):
Anaconda 16.XX (as supplied in Fedora 16 Alpha (RC5))

How reproducible:
Always occurs

Steps to Reproduce:
1. Choose custom partitioning layout with a /boot (or / if no /boot is listed) partition formatted as btrfs.
2. Once finished listing partitions, click next to format them.

Actual results:
Anaconda warns that /boot can't be formatted as btrfs, and returns the user to the custom partitioning layout.

Expected results:
The partitions are formatted, and the user enters the next stage of the installation.
