fsck.btrfs

I am new to btrfs and have begun exploring and testing it.  One of these tests is to install Fedora 18 into a btrfs volume only leaving /boot and swap on regular partitions.  BTW, this is on qemu/kvm/libvirt virtuals.

I discovered an error was occurring during bootup because systemd was attempting to start fsck.btrfs and it was missing.

1. Would btrfsck be the appropriate program to run at bootup?  If it is, with what parameters?

2.  Should there be a fsck.btrfs but it has not been written yet?

3. Does btrfs even need a "fsck.btrfs"?

I get the distinct impression that "btrfs is not your father's filesystem" and thus need to be looked at very differently.
