Harald posted a blog story about this a while back:

I guess we could do an updated version for F16 of that since a couple of
thing changed since then. For example the SELinux policy got updated now
so that initrd-less boots do not trigger selinux faults anymore. In
fact, initrd-less boots work really nicely nowadays, the only two
missing bit to maybe make it a default is basically that a) the kernel
cannot boot into a partition by UUID, only by logic name which is a bit
fragile [1] and b) Plymouth currently doesn't cope nicely with it since
it's called before the video devices are probed if used without an
initrd.

[1] What the kernel can do nowadays is mount a GUID partition by the
GUID, which might be a pretty good replacement -- at least on machines
which have a GUID partition table.
