fyi: i have a 98/2k/fc3 install. grub options are fc3 and 2k (nt bootloader has the choice between 98 and 2k). 2k is the default, configured that way during installation. upgrading the kernel changes the grub default from windows to whatever the new kernel is. i have to manually change the default back to windows. this has happened both times i've fetched kernel updates (via up2date).
