Linux tester and linuxator for donated computers
A lot of older computers that people are ready to throw away can be decent linux boxes, in schools or in other charitable locations.
I propose a simple small program (possibly fitting on a floppy as well as CD) which can be inserted into an old computer. It scans the harware and compares it with hardware databases of chipsets, cards and other parts which are known to work well under linux (or your favourite BSD or other OS) and to work well together. It would also evaluate the machine and put it in a "performance class" to describe just how good it is. It might connect to the net (if it can) to download the latest such lists and info and software updates.
The goal is to test if the machine can do a problem-free install, one that asks almost no questions, and converts the system to a nice linux box, ready for some student to run for e-mail, web, and writing. There are so many machines to donate that we can insist on perfection. The program could also tell the owner what upgrades it might need to be good or to reach a performance class. "This machine is good but with 128M of ram it would reach performance class N." "This machine would be perfect if you swapped the ethernet card for one of these models" and so on.
Next, of course, is a simple distribution, to install from CD-rom or over the network, that can be quickly installed with no questions asked except perhaps time-zone (if it can't figure that out from the old OS.) The goal is a system that can be run by untrained admins who may never have seen the insides of linux or any other OS.
