The liveinit script is a template too and cannot be used as-is.

This file was forgotten in the previous commit.
It has now also been given a '.tpl' extension in the liveslak sources,
to indicate that it is a template and not usable as-is.
The 'make_slackware_live.sh' script parses the template file and performs
a series of variable substitutions to generate the final 'init' script
inside the initrd of the ISO image.

+# Changelog
+# 10-Dec-2012 <mozes@slackware.com>
+#  * Added support for the official Kernel parameters to select root filesystem
+#    type ('rootfstype') and pause before attempting to mount the root filesystem
+#    ('rootdelay').  The original parameters may continue to be used.
+# 23-Oct-2015 <alien@slackware.com>
+#  * Modified for booting as a Live filesystem.
+##################################################################################
+
+# The ISO creation script will create a filesystem with this label.
+# Nevertheless, the user may have copied the ISO content to a different device.
