Alas, I think I've solved this problem in the wrong place. The real
problem is that the LVM startup script on Debian that runs prior to the
mountall script doesn't add the --mknodes flag when it runs vgscan.

I think that's the correct place to have it fix the device entries. I'm
working with the maintainer of the lvm-common debian package now to see
if we can get the fix rolled into their package.

So the only change that should be needed to Miguel's script is to add
/initrd entries to the PATH.

Cheers,
Jeff
