It can only handle small patches which don't change

And to date there hasn't really been any compelling reason to issue tiny
patch security-updated kernels, 'cause you have to reboot anyway, right?
But as the technology improves, more opportunities arise.
I recall deploying some sort of hack workaround for the vmsplice exploit
a while back on a whole bunch of machines (Fedora or downstreams) that
were going to need a reboot scheduled up to a week in the future. This
kind of technology would have been really swell to have then.
Lots of reasons to not want to reboot machines - most of the arguments
for supporting laptop suspend would fit. Some of them may fall into the
"protecting users from themselves" category, but that's not a bad thing
either.
