After hours of trying to preseed the Debian installer i got the results i wanted. The text based installation is ready now, but for the graphical one i had to start Gimp and swing the brush 🙂 The installation process is reduced to the minimum to allow everybody to install OMV. The only interaction to be done is to set the hostname, a static IP address if DHCP does not work and finally select the harddisk used to install OMV. Voila, after some minutes OMV should be on the harddisk and ready to use.
While playing with the new firewall WebUI i found out that it is crap because the user is not able to rearrange the rule order. Because of that i had to rewrite the UI the next days to get this working.
