   What I'd do is decide what non-kernel services I want to run; e.g., httpd,
sshd, postfix, whatever. That is, what do you want this machine to do. Then
I would explicitly enable those services and leave the rest as they are.

   As I understand the point of the exercise is to see if this host somehow
causes the network printer to rumble and complain now and then. If that's
the case, then let's focus on what might be doing this -- CUPS -- and ignore
the rest for now.

   chmod a-x rc.<whatever>

   This makes them non-executable. Also, look in /etc/rc.d/rc.local and see
what that loads at the end of the boot process.

   Isn't this one of Frank Zappa's kids?
