Dear Sir:
Thank you, I will download and try it. I am using Mandrake 8.0 (2.4.8-12mdk) and the latest mandrake release of LVM (09.2 I think?).

Subject: Re: [linux-lvm] How to boot with LVM?
If it's any help, I have put my initrd on public ftp at
fruits.foobarhouse.com in the LVM directory. It's served me well for as long
as I've been using LVM'ed root.
I'm currently using LVM 0.9.1beta8.
Regards,
--Neil.
