That may not be wise. Back in the days of 2.0.5, or 2.1.0, I upgraded this system from 16M w/ 32M swap to 48M RAM. Forgot to add swap. And it died in "make world" when it ran out of core. Then I added my swap partition and re-executed "make world" while watching memory use on another virtual console with top. Never did see more than 400k or so swapped. Of course I didn't sit there for hours (3 or 4 hours, back then, same system now takes 7) and watch it altho the original failure happened fairly quickly. I'd guess even a 1G RAM system would work best with a little swap, say 64M, if for no other reason than to initialize the same virtual memory paths everyone else has. But that's only superstitious guessing. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
