#
# This script is designed to facilitate in-tree development and testing
# by installing symlinks on your system which refer to in-tree helper
# utilities. These helper utilities must be installed to in order to
# exercise all ZFS functionality. By using symbolic links and keeping
# the scripts in-tree during development they can be easily modified
# and those changes tracked.
#
# Use the following configuration option to override the installation
# paths for these scripts. The correct path is automatically set for
# most distributions but you can optionally set it for your environment.
#
# --with-mounthelperdir=DIR install mount.zfs in dir [/sbin]
# --with-udevdir=DIR install udev helpers [default=check]
# --with-udevruledir=DIR install udev rules [default=UDEVDIR/rules.d]
# --sysconfdir=DIR install zfs configuration files [PREFIX/etc]
