No, this is just the wrong way. The kernel is the most important part for a running system. You can turn off samba, or cron, but turning off the kernel is ... *mmmhh* ... stupid ..
ssh? cron? syslog? ntp?
Everyone caring a little bit, should be able to recompile a kernel, and it is not very hard to learn, too. Distributors will _never_ be fast enough to rapair a kernel hole in reasonable time. As far as I remember, SuSe has made a patched 2.2.18 kernel, which _is_ secure.
I must disagree on this point. Does everyone that drives a car know how to fix it? I sure don't. Do you know how to safely disable the airbags in a car? Can you do basic TV repair? Microwaves? Computers are horribly complex, most people quite simply don't have the time, expertise or want/need to learn, and they don't really need it to be honest. This is why we have tech support and IT staffers. BTW what happens when there is a flaw in binary only software? Doh. I think Theo de Radt has a good quote on this "we don't want administrators to have to be security experts, that's why we ship OpenBSD secure by default".
