2#
3# This script is designed to facilitate in-tree development and testing
4# by installing symlinks on your system which refer to in-tree helper
5# utilities.  These helper utilities must be installed to in order to
6# exercise all ZFS functionality.  By using symbolic links and keeping
7# the scripts in-tree during development they can be easily modified
8# and those changes tracked.
9#
10# Use the following configuration option to override the installation
11# paths for these scripts.  The correct path is automatically set for
12# most distributions but you can optionally set it for your environment.
13#
14#   --with-mounthelperdir=DIR  install mount.zfs in dir [/sbin]
15#   --with-udevdir=DIR         install udev helpers [default=check]
16#   --with-udevruledir=DIR     install udev rules [default=UDEVDIR/rules.d]
17#   --sysconfdir=DIR           install zfs configuration files [PREFIX/etc]
