Assuming hardware failure is not a factor, and the requirement of being able to update periodically, is it possible to never shutdown Linux?
I typically do a full reboot after updates, especially kernel updates, but is there a way to keep my machine on and still do these? People always hear about incredible up-time, but how is that really possible if you must reboot after major updates.
Maybe a different run level? But then how would the kernel update kick in?
