Many have said that an example is worth a thousand words. But in this case, example also has the documentation with it. The easiest way to create a Scientific Linux site is to copy example, and to follow it's instructions.

Scientific Linux 6.x

Scientific Linux 5.x
Under Construction

Quick Steps

Before You Start
• These steps must be done on a system that is installed with Scientific Linux 5. That system must have anaconda and anaconda-runtime installed.
• You must have a mirror of the SL distribution you are basing your site on.
  You have to have the sites/example directory mirrored

Definitions
• *newsite* - name of the new site you are making
• *basedir* - Directory where you have your distribution mirrored
  example - /mnt/src/sl/53/i386/

Steps
1. cd *basedir*/sites
2. cp -rp example *newsite*
