It can be surprising what it asks for though. When I did my first update
with rpm fusion I had forgotten to import the rpm fusion keys. But using
yum with the -y option had it do the update despite this and the message
indicated it did the import as well (though I haven't verified it).
My expectation was that -y was just OK'ing a list of updates, not bypassing
security checks.
