When UPDATEDEFAULT=yes the default boot selection in
/boot/grub/menu.lst will be set to point to the newly installed
kernel. If you are dual booting and want a different OS or a
particular kernel to be the default then set UPDATEDEFAULT=no so that
kernel updates will not change your boot selection.
