I used to use Virtualmin to run my dev server. It has a lot of options available on the web interface, and that was very handy. In preparing a new dev server, I like the Drupal 6 appliance idea. I have it, installed and working fine.

Virtualmin had a wonderful little script(s) so that when you added a new domain to the lot, all kind of administrative tasks were automatically handled. I can't imagine this is out of reach for the turnkey appliances and I'd like to know how I can make one myself. For example, adding a domain adds a user, a home folder with a skeleton directories like logs/, public_html/, svn/, etc/, some apache directives and seperate apache config file, etc.

In the webmin included with the turnkey appliance, where would I start to begin working on a similar script? Obviously it won't be as serious as Virtualmin's, but I'd like to set some things up when I add another user/domain to the mix, without having to do it all manually. Possible?
