The kernel then IGNORES the size extents set for the swap partition (in this case FC2 was set to 1024, FC4 was set to 2048) and allows the cross mounted swap to grow into the next partition, totally corrupting the root drive (/) by allowing the swap segment to grow into the root drive and overwrite it. To reproduce, install FC2 on an /dev/hda device with defaults, then install FC4 on a /dev/hdb device, build the 2.6.14 update for FC4 and watch your data disappear. Jeff
