Your friend has absolutely no idea what he's talking about. In any traditional Unix system (V6, V7, Sys[35], BSD), the kernel is never swapped. If you don't have enough physical memory to hold the kernel, you can't boot. Seems to me maybe he should have actually done some research before writing this "paper". Good places to start would be Bach's "Design of the Unix Operating System", Leffler, et.al. "The Design and Implimentation of the Unix Operating System" and Quarterman, et.al., "4.2BSD and 4.3BSD as Examples of the Unix Operating System" in ACM Computing Surveys, December, 1985. -- ken seefried iii "I'll have what the gentleman ken@dali.cc.gatech.edu on the floor is having..."
