The only thing you may NEVER upgrade using -U or -F is the kernel.
Suppose that the new kernel isn't working properly, you can't roll
back because upgrading removes all the previous file(s). You want to
use -i (install) so that the new kernel is installed alongside the
current one (kernel is the one exception with respect to install
alongside an existing one).
