The updated lvm package at Arjan's site has the man pages omitted, hence
no conflict if one upgrades to that version.

I think I covered the required steps in the first half of that email.
There are one or two small thinkos (namely dm-mod.o -> dm-mod.ko, and
lvm.c should not be included in file glob in the discussion of patching
in device-mapper.)

If you want to boot back and forth between 2.4 and 2.5, you'll have to
hack up rc.sysinit or use device-mapper on 2.4.  Rather than rc.sysinit
trying to find the device file for the root filesystem on the root
filesystem, it would seem to make more sense to defer unmounting /initrd,
and use the device file there instead to do the fsck.  I haven't bothered
to create that patch, but it should be is pretty straightforward.
