I wasn't sure when I created this if it would be of interest to the community, but please find attached my HAProxy Init script. It supports both reloading and the "fancy green OK output" ;-).
Usage:
1. Update the user configuration section of the script with the path's to
your HAProxy binary and configuration file
2. Copy into /etc/init.d and name the file "haproxy"
3. Set the permissions to Executable ("chmod +x haproxy")
4. On a Redhat/Fedora system, configure it for use by running "chkconfig
--add haproxy" and then to get it to start, "chkconfig haproxy on".
5. Then use "service haproxy start" to run HAProxy.
Hope this helps!
Robert.

I don't know for the colors, but I have comments below

here you use $BASENAME ...

don't do that. If you add sleep, it will only make things work by pure luck
and slow your system down for nothing.
> pidof haproxy > /var/run/$BASENAME.pid
better use -p /var/run/$BASENAME.pid like this :
/usr/local/sbin/haproxy -D -f /etc/haproxy/haproxy.cfg -p
/var/run/haproxy.pid -sf $(cat /var/run/haproxy.pid 2>/dev/null)
That way haproxy sets the pid(s) file itself and checks that file, it does
not rely on a tricky "pidof" call nor the presence of a "sleep" call.
