[linux-lvm] Initrd, usefull ?

[Georges Giralt]

Hello !
I plan to convert my Redhat 7.1 (ugraded from RH 4.2 through all versions 
in between....) to a root LVM.
I've got the latest LVM code, patched my 2.4.5 kernel, compiled without 
optimization to make lvcreate run ;-)
And wonder if I _really_ need an initrd, if I put the LVM code straight into the 
kernel.
I'm of course aware that I need a modified Lilo able to understant the LVM meta 
data, in order to find the kernel. But once this is done, what will the initrd 
be used for ?
Any information, hints, tips would be greatly appreciated !
