On two different fedora 8 systems (which happen to have other boot partitions as well to different linux distros), I have rebooted recently and gotten fsck problems on reboot to fedora 8 with the message: primary superblock features different from backup, check forced. Anyone know what the heck that is all about? Is fedora 8 ext3 different than fedora 7 ext3 (or ubuntu ext3)? Seems to have been harmless (no problems have cropped up anyway), but I'd rather not fsck all my disks every time I boot a different OS :-).
