Hey Harald and all,
We're not trying to keep the Script Installers API shrouded in mystery...we just haven't had time to write it up yet. We
want folks to start developing additional installers (and it's not at all unlikely that the Script Installers interface, if not the actual installer scripts, will trickle down to GPL sooner than most Professional features because it is so potentially useful to users and developers alike).
When the feature was first added, I wrote up a quickie post about working with it here:
http://www.virtualmin.com/forums/message-view?message%5fid=3317It does tell you where to find them, and give you a few hints about how Jamie approached the installation process. Obviously, the simpler a script is to install, the easier it is to write a Script Installer script for it, but there are no limits to how complex the process can be.
Once developed, the script installer can be distributed to other Virtualmin users who can install it without ever having to hit the command line. Jamie really outdid himself on the Script Installers.
If you have questions about how to write your own, please let me know in the Developers forum. Worst case scenario, I won't know the answer and I'll ping Jamie to come chime in--he's certain to know. ;-)
