I think it's reasonable to configure a swapless system if it has a
large amount of memory... for example, more then a gigabyte. I don't
think it's critical that we 'fix' the safety check for the 5.0 release
though. Swap is generally a good thing no matter how much memory you
have because the ability of the system to page-out totally idle pages
(like pages from getty's and other system daemons that are typically
always idle) allows that ram to be reused for additional disk cache.
A system with only 192MB of ram should definitely have swap. It may
sound like a lot but you will use every drop of it if you install certain
large workstation programs like Gimp or OpenOffice and having swap will
make those programs work better. It depends on the eye of the beholder,
I suppose.
