Every good sysop I've met can write your Chef code. Understanding system basics and managing with high level tools is not mutually exclusive. Tools like Chef are the result of exactly those sysops automating what they could. You know that saying? "Tomorrow I'll replace you with a shell script." ;)

Yes, I only update when a security problem concerns me and that is pretty rare with custom kernels that only have what is required. Even my desktop setups need a new kernel only once a year or so.
