"I don't expect" is an idiomatic form of "I estimate a low probability of swapping". > I'm not sure if you can omit it. Haven't done an actual NanoBSD installation on flash, but my reading of the setup is that there is no swap partition whatsoever. Guess I'll have to experiment to find out for myself. > > 3.

Just wanted to be sure. I'm still open to using md devices for /var and /tmp (with a cron-ed sync to disk) possibly in conjunction with remote logging, but one of the reasons I opted for SSD over regular flash is to avoid that extra layer of complexity.
