But UNIX=m == waste RAM and have an effectively b0rken system until the module is loaded. It would be silly to do this unless you have a very small space for the kernel image and some free space for storing the needed modules. The big question is: Is there any non-embedded system where you have to aim for a small kernel image? -- Fun things to slip into your budget Half a million dollars for consultants to design a web site that was being done by an intern in his spare time.
