- The kernel will warn you if swap space is < physical memory. The consensus
- seems to be that for SunOS 4.x you want swap space to be at least 2.5 meg
- bigger than physical memory.
-
- Since SysV machines tend to treat swap space as overflow instead of as backing
- store, the 5.x virtual memory size may be ~ physmem+swap.
