On a Linux system, you are right. Systems that people tend to think of
include SunOS (where the swap area _had_ to be at least the size of
physical memory), and systems that can do core dumps of the
kernel. Since Linux (at least not to my knowledge) cannot do core
dumps of the kernel, the size of the swap area(s) are irrelevant
compared to the physical memory size.
Speaking of core dumps, have anyone considered the idea of making the
kernel do core dumps? It would be nice to have a run-time option
(/proc/sys/kernel/coredump?) that could tell the kernel when to core
dump. Panics and Oopses are situations where you sometimes would need
core dumps.
