Ahhh, but you just defeated the ideal of being able to customize to task. This is where the hallowed "the user is dumb" theory bites us in the ass. A single option to control all these sizing issues reduces flexibility and that is what the embedded system designer is looking for. The ideal situation is if as we work on all these areas where we can reduce size, we provide fine grained options to tweak them (with a default desktop/server value and a default "tiny" value). You can have this CONFIG_TINY or whatever, but then we should also provide the ability to tweak the values exactly how we want in a specific application. The tweaking options can be buried under advanced kernel options with the appropriate disclaimers about shooting yourself in the foot. Regards, -- Matt Porter porter@cox.net This is Linux Country.
