if your web server is configured properly, all you have to do is to copy the wipha folder created in the Sites folder from a sandard install.
I might consider trying to adapt the installer so that it detects osx workstation or server, but I need some info about the server version:
- directories structure (which differences with the workstation version)?
- where is located the default web site folder ?
- what are their owner/group/permissions ?
- Which command could allow to distinguish the 2 versions ? --> Could you give me the output of "uname -a" ?
