Do _NOT_ use this for kernel installs/upgrades. _Always_
use 'rpm -ivh'.

There is no 'might' about this. It _is_ the way to proceed.
The simple reason is that the kernel you are running has
proved to bootable. If you upgrade (-Uvh|-Fvh) and that
kernel does not boot, you may have to go thru a lot to
get a bootable on your system. Depending on the level of
expertise of the user, this can be a daunting taks,

Not in all cases. For instance different versions of python or db
can exist installed on a machine. It all depends on how the software 
is packaged.
