NOTE: rhbz#1033764 is currently defined as an "Accepted Freeze
Exception" for Fedora 20 Final BLockers.
This pair of updates addresses the problems documented by
rhbz#1036903 and rhbz#1033764.
The first problem is that "ro" is not specified as a kernel parameter.
The second problem is for the situation with the rootfs ("/") is
on a BTRFS subvolume. In that case, there needs to be the
kernel parameter rootflags=subvol=<name> where <name? is the name
of the subvolume.
Thanks for the patches - I've pushed to branches as appropriate.
