Daemontools

daemontools is a collection of tools for managing UNIX services that was created by Daniel J. Bernstein.

To simplify management of the various daemons on the server, install daemontools. Asides from some other benefits, a really nice thing about daemontools is that gives a consistent means of managing different services rather than a mish-mosh of different init scripts, rc.d scripts, etc.

Installation
Setup a directory to download your source file into:

mkdir -p /package
chmod 1755 /package
cd /package
