Looking at how my servers update themselves and the recent Copy Fail vulnerability, I'm considering an automated weekly restart to make sure services and kernels are up to date. It'd also ensure that services are correctly configured to start on boot.
Any thoughts? Feels crude.
I admire hobbyists who build their own kernels, but the size of modern systems is intimidating. Even something like a Bluetooth stack is bigger than historic kernels, and tends to require multiple people.
I think it's just the cost of compatibility? Tech collaboration is hard.
I've been thinking more about this viewpoint, and I think both simple kernels and simple browsers are possible for an enthusiastic hobbyist.
