If you build nearly everything (except, obviously what you need to boot) as
modules, you can unload modules, build new versions, and reload them. So,
you could say that partial support for "live upgrades" is included.

It works, too - I unloaded my OV511 driver a few weeks ago, copied the
source for the new one in, built it, and re-inserted it. Same goes for the
DRM module a couple of weeks before that. Now, the machine in question
gets rebooted fairly often in any case, but those were things I *didn't*
have to reboot for.
