  Mounting the new partition on /usr will hide the original /usr. You must
  use a different mount point.

  Note: using newfs is DANGEROUS! Be very careful with these steps or you
  might loose important data! I am not responsible for any damage!

  Here we go (do these steps as root):

  Before we start, remember that adding/removing a partition changes the
  disklayout. That means that it might be necessary that you adjust your
  /etc/fstab. You will find out if NetBSD doesn't boot into multiuser
  anymore...

  Find out exactly which partition is your _NEW_ NBU\07 partition:

   disklabel /dev/r<your disk>

  You can identify the partition by its type (something like BSD4.2 and/or
  by the used cylinders).
  Then you have to initialize the filesystem with newfs eg.

    newfs /dev/<whatever disklabel told you>

  Then you can mount the partition, eg:

   mount -o softdep /dev/<new partition> /<mountpoint>
