Bootscript
The following bootscript is only needed in a very specific situation, If you use an initramfs or some other early userspace to initialize lvm2 device nodes. This script only runs vgscan --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
