Here is patch that Yang sent. They used this patch for Meego but I'm
not sure if it handles all issues because ther image is not btrfs even
it can be installed only on ext3 formated partition and not on btrfs
last time I checked:

Is this patch in latest mkliveinitrd in rawhide?

Mkinitrd has an issue for btrfs, here is the patch:

diff --git a/mkliveinitrd b/mkliveinitrd
index 66167be..ba575b4 100755
--- a/mkliveinitrd
+++ b/mkliveinitrd
@@ -667,7 +667,7 @@ do_live_from_base_loop() {

    # set up new /dev/root symlink
    rm -f /dev/root
-    ln -s /dev/mapper/live-rw /dev/root
+    ln -fs /dev/mapper/live-rw /dev/root

    mount -n  /dev/mapper/live-rw /sysroot
    # here you can modify the rw ext3 fs for testing if you don't want to

I don't know wht it is so, but it is really so :-)

For anaconda, I think you need to do some changes, but with this
patch, your live image should be able to boot normally."
