vardir — Shorewall Lite file
/etc/shorewall-lite/vardir 
This file does not exist by default. You may create the file if you
    want to change the directory used by Shorewall Lite to store state
    information, including compiled firewall scripts. By default, the
    directory used is /var/lib/shorewall-lite/.
The file contains a single variable assignment:
VARDIR=directory
where directory is the name of a
    directory. If you add this file, you should copy the files from
    /var/lib/shorewall-lite to the new directory before
    performing a shorewall-lite restart.
