It is intended to save my little trouble in typing installation repository path and choosing timezones only and do nothing else. All other options would be asked interactively, including disk partition. (timezone and installation repository are the only options that are absolutely the same in every machine in a local environment :) ) Since this problem doesn't occur in 6.1, is it possible to be a installer bug in 6.2?
