this tool is mainly for ASP.Net running on IIS.
OpenPetra at the moment is a client server application.
I am working on the server part to be a ASP.net application, but it is not in trunk yet. And even then I am not planning on supporting IIS, but fastcgi-mono-server4. Not sure what the longterm plans of OM are regarding the server OS.
And the client is still a fat client for the foreseeable future, we are using InnoSetup for the installer, and nant to build it.
For the server I have in my branch a nant task to create a tar file that can easily bundled into a debian or centos package. I want to use Open Build Service for building the linux packages.
see first experiments at build.opensuse.org/package/show ... postgresql
eg build.opensuse.org/package/view ... c?expand=1 calls nant buildServerCentOSPostgresqlOBS
All the best,
