ext2 partitions tha exist previous to installation, and are then selected as mount points in disk druid are automatically tagged by disk druid to be formated on the next screen. This is really bad, if the drive has existing data on it, and a person accidentally does not deselect the format (lucky I didn't :)
It is recommended that all partitions be formatted prior to use under linux, and this is why the partitions default to the check mark. There is a larger group of people that would forget to check those boxes to format the partitions than would forget to uncheck the box to prevent formatting, so the Red Hat installer defaults to formatting ext2 filesystems. This is not a bug as it is the desired behavior of the installer.
Not a bug? Maybe not if you define bug as "programming error", but in my strong opinion, this is a clear design flaw. Although, I suppose I am biased, having just wiped out several gigs of personal files. Please, PLEASE give more feedback to the user when you are about to format a partition. Whenever partitions are to be formatted, a screen should be presented indicating in large text what is to be formatted, and requiring the user to acknowledge before continuing. Please, reopen this ticket and do something about it. I don't want anyone else to go through the agony that I just experienced, and such poor design does not reflect well on RedHat.
