By default, a kickstart installation will spread the configured partitions over all disks that are found, and the only way around that is to use --ondisk or ignoredisk. But I was wondering how reliable this method is. E.g. if there are four SATA ports on the system board, can I blindly assume that port one will always correspond to sda, port two to sdb, and so on? Can I assume that a second disk added to a one-disk system will always show up as sdb, and sda will remain sda?
