Bootscript
The following bootscript is only needed in a very specific situation, If you use an initramfs or some other early userspace to initialize device mapper. This script only runs dmsetup mknodes and reports the status of the command on start. If you need this functionality, install the bootscript with the following command:
cat > /etc/rc.d/init.d/lvm2 << EOF
#!/bin/bash
