https://bugzilla.redhat.com/show_bug.cgi?id=484522 is the bug in
question; Eric, if it's fixed, could you update the bug?

Oh, and by the way.. if you're like me, and you're installing from the
Live image anyway, you might think: "Hey, I'll migrate the filesystem
after the install finishes, before I reboot into the new system". Nice
idea, but if you don't rebuild the initrd after migrating the rootfs to
ext4, the system won't boot. Yeah, found that out the hard way.

The steps go something like:
1) mount -t ext4 $rootdev /mnt/tmp
2) bind-mount dev+proc+sys, chroot /mnt/tmp
3) edit /etc/fstab and change the entry for your root device to ext4
4) mount /boot and recreate initrd
5) exit chroot, umount /mnt/tmp
6) tune2fs -O extents $rootdev

..yeah, it's kind of complicated. You're better off getting a different
installer image, or waiting for Beta.
