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
########################################################################
# Begin $rc_base/init.d/lvm2
#
# Description : Creates lvm2 nodes that may have been created in an
#               early userspace.

		echo "Usage: ${0} {start}"
		exit 1
