I'm running Zimbra 8.0.4 OSE. I have the production server synchronizing with a backup server on a regular basis. I have things set up so if I'm away on vacation and the production Zimbra server dies, my co-workers can bring up the backup server. Part of the process of bringing up the backup server is running the Zimbra installer. Is it possible to run the install.sh script without prompting for Y/N questions?
