I haven't used Fedora's grub2 enough to go through a kernel upgrade
and be able to tell you whether "grub2-mkconfig..." is run
automatically to update "grub.cfg" but given that grub1 updates
grub.conf automatically and grub2 on Debian and Ubuntu update grub.cfg
automatically, you can be quite confident that Fedora'll make sure
that his happens.

Someone (I assume that he is affiliated with Fedora or Red Hat) listed
some enhancements that Fedora'll have to make before grub2 becomes
more than a something to test. I guess that we can add to his list the
automatic update of grub.cfg and the migration of the grub1 boot
params when grub2 is installed on a box that had grub1 already
