The only time you truly need to reboot is when you update your kernel.
The solution to this problem is live-patching. Not really a game changer with consumer electronics because they don't have to use ECC, but with servers that can take upwards of 10 minutes to reboot, it is a game changer.
We have an Ubuntu machine at work with an NVIDIA GPU we use for CUDA. Every time CUDA has an update, CUDA throws obtuse errors until reboot.
To say only kernel updates require reboot is naive.
Damn yeah I didn't think of that either. Alright, scratch what I said. The point still stands that you very rarely need to update outside of scenarios containing very critical processes such as these, those of which depend on what work you do with it.
It's been a long slow night and morning and I was half awake when I said that. Hell I'm still half awake now, just disregard anything I've said.
This isn't true, I had to reboot debian the other day to take an update to dbus which is not part of the kernel.
