Sometimes all you want to do is add a couple files to Salix Live, for example specific configuration files. In that case it is not necessary to create or modify a module.

Salix Live CD holds a /salixlive/rootcopy/ directory. The content of this directory is copied to the root filesystem each time you boot, preserving all directories.

So, for example, if you wish to just use your own xorg.conf file, create etc/X11/ directories inside of /salixlive/rootcopy and store your xorg.conf in it. Note that you need to recreate the full directory hierarchy for the patches to work as desired.
