Well, I see the intent behind package-kit, there's a lot of people out there that just won't update,
until you have the system go out of it's way, look for updates then then bug them.
packake-kit is kind of like yum-updated but with more feedback.
Not updating causes big problems with security holes that never get fixed. So package-kit
just makes it stick out more. One thing I do think is nice with it is it shows the
reason for the update on each package. Yumex has the same feature but
usually it just has the canned description, ie it says what the package is
but not why it's being updated. It is a critical security fix or just a mundane
feature updated? The fields that would do this in yumex (changelog and other)
are usually empty.
