I don't like this one bit. Things used to be simple with the "split" between
/bin and /usr/bin (and its related directories), this isn't going to make it
more simple.

I use a separate /usr with LVM on all my systems. My root partition uses
RAID1. And I never had the need for an initramfs of any kind. Also, there
are some major hurdles to take when it comes to getting an initramfs working
with SELinux. Most initramfs implementations I saw are not SELinux aware, so
all changes they make to the system either result in failures when they try,
or failures when the root-switch occurs.

I'm all for this one. 

But if people really want to focus on initramfs, I'd appreciate some
documentation help on it. Not only on how to create one, but also why it is
necessary, how to manage initramfs'es, the concepts underlying, etc.
