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. Wkr, Sven Vermeulen
