Without more information about your setup it's not possible to be more
specific but I've done this on several occasions by using the "Custom
partitioning" or whatever the setting is in Anaconda and carefully
setting everything up and only formatting the volumes for "/" and
"/boot" and just labeling the others. In my case "/home" and "/var".
