New LVM2/device-mapper development tarballs - works with kernel from Linus?

[Piet Delaney <piet@bluelane.com>]

  I just tried dm-crypt and there appears to have been a change in the 
/dev interface. 

In 2.6.13 and linux-2.6.18 I'm seeing a /dev/device-mapper file. 

  crw-rw----  1 root root 10, 63 2006-09-12 21:33 /dev/device-mapper

Note NOT a directory.

The docs from Redhat device-mapper.0.96.03 thru device-mapper.1.02.09 all
seem to say:

   /dev/mapper was called /dev/device-mapper prior to 0.96.04.
   Consequently scripts/devmap_mknod.sh has been updated.

and seem to expect a DIRECTORY. Maybe this is a udev problem,
but I suspect it's a device-mapper problem. Perhaps I need
to go back before 0.96.03.

I'll look into the new New LVM2/device-mapper development tarballs;
my guess is it doesn't work with Linus kernel on kernel.org.
