#
# This script (which must be sourced and not executed)
# checks kernel version and modifies PATH to use lvm2
# when linux-2.6 is detected.
#
# It creates a directory containing symlinks to /sbin/lvm2
# and inserts it in $PATH as first element.
#
# Thus calling vgscan, vgchange, vgdisplay and so on
# calls the lvm2 binary - when kernel version is 2.6.
