I believe that all answers to this question have been given so hopefully
you don't mind if I hijack this thread...

Since we're in the middle of discussing LVM, I've got a request.
Not too long ago, I had my root partition "/" on an LVM physical volume.
It was actually pretty easy to set up and worked like a charm until I
created a snapshot of one of my other PVs. As soon as I did so, I could
no longer boot the system because the dm_snapshot kernel module was not
loaded. I was told by several people that I needed to add a "hook" for
it, but never did figure out how to do so.
It seems to me that if we are going to support booting from logical
volumes, we also need to make sure that users who do so are still able
to boot if they decide to take a snapshot of any logical volumes,
including booting from a snapshot of "/".
I'll be glad to help test and even work on the hook if anyone gives me
instructions detailing how to do so.
Thanks!
