Thanks for confirming this. I think I may have read something about this last
year when I first researched LVM but then forgot.
As for not using an initrd.img, long ago I became a confirmed follower of the
KISS theory of operations (Keep It Simple, Stupid) and was just trying to
pare my kernel of any unnecessary pieces. But, as you say, it's not that much
trouble to maintain an initrd.img.
