Shorewall users - Jun 2003 - Speeding up [re]start

While I was doing come compatibility testing with various shells, I
noticed the following:

Using /bin/sh (which is ''bash'' on my RedHat installation):

Shorewall Restarted

real    0m21.246s
user    0m9.650s
sys     0m11.460s

Using /bin/ash:

Shorewall Restarted

real    0m9.054s
user    0m3.880s
sys     0m5.070s

The version of ash that I used is the one available from the Shorewall
download sites in the /pub/shorewall directory.

To use ash, I made the following changes:

1) I edited /usr/share/shorewall/firewall and changed the first line to
"#!/bin/ash"

2) I run WonderShaper which I''ve installed in /etc/shorewall/tcstart. I
edited that file and changed two instances of "$[...]" to
"$((...))".
