Hi, with the pm-hibernate support in FC5, I never switch off my laptop, I just hibernate it. Big mistake when upgrading Fedora: the CDs don't detect the hibernation. They mount disks, and then decide that the swap space sig is broken. After a reboot the dehibernated system gets completely confused, because of the FS was mounted r/w by anaconda.
Hrm, we should probably do something about this for FC6. Our current upgrade finding is "look for filesystems we can mount, read /etc/fstab". I guess we should add a "find all swaps, see if they're swsusp, warn really loud" and then what we currently do
Fixed in rawhide. If a swap partition has a software suspend signature, a dialog pops up explaining the situation. You can skip the partition and the installer won't do anything with it, you can format it as swap and continue, or you can reboot.
