Your on the fly control system should not use toggles
Here's a request to programmers: if you are building a system withsome form of dynamic control and adjustment commands, like Bind 9 andits rndc program for controlling the daemon's behavior on the fly,your interface should not include 'toggles', commands or options thatinvert the current state of a setting. In rndc , an example is ' rndcquerylog '; this turns DNS query logging on if it is off, and turns itoff if it is on.
(In fact this extends to
Some notes on (dynamic) Bind 9 logging
Bind 9's rndc has tasty looking options to change and increase loggingon the fly, which is just what you want if you're trying to track downan erratic behavior in a caching nameserver (where restarting the servermight well make the whole thing go away so you can't troubleshoot what'sgoing on). However, it turns out that you need some Bind configurationoptions already configured in order to make it work. Since I just wentthrough figuring this out (and I may need to

Another reason why I don't like Ubuntu kernel packaging
I've written before about theover-arching problems with how Debian and Ubuntu package kernels, buttoday I ran into another annoying issue with how Ubuntu handles theirkernel packaging mess.
The problem Ubuntu has is that their kernel packages need to have thekernel version as part of the package name, but they want to createa simple way of upgrading from kernel to kernel without too muchspecial magic in the tools (as an entirely new package, a new kernelis not an upgrade for any existing package so package
