Hi Dave. I don't work with embedded systems. I've been careful to make my recommendations for servers only. Having said that I think that embedded systems would in general be running swapless for the reasons you mention. > So, if you say that a system without any "swap" misbehaves, how does a > system like this survive? Linux can survive quite happily without swap as long as it doesn't run out of memory. This should generally be true for any modern *nix I think. Older OSes would actually fall over if they did not have sufficient swap available. An embedded system is far more deterministic than a general purpose server. As such its memory requirements should be able to be estimated fairly accurately and sufficient ram can be allocated. Thus I don't see this as being a problem for embedded systems - says the guy who doesn't play with them.
