Is it possible to add by default in a freshly installed Alfresco (3.0 Stable) a new user group (like SYSTEM_ADMINISTRATORS) and automatically add the 'admin' user? Perhaps through a bootstrap xml file? I really don't know which.
Why add a configuration parameter? You can implement an Alfresco Module Package that executes in the init method all that you need for your business features using the Foundation API.
Could you please be a little more specific? I've never built custom AMPs.
I thought there was a shortest way to go, because I just need to create one group and add one users and I'd rather not write a module just for this. But if it's the only one, I think I should go through it!
