Just FYI based on my experience: 32MB possible with extremely tuned system. Lots of effort. Experts only, = and even then it is hard. 64MB possible with tuning and turning things off. Fair amount of effort, = not so hard, but far from easy. 128MB works reasonably well, some tuning needed. A little bit of effort, = but not too hard. 256MB is easy without a GUI, but still too small to rebuild FreeBSD = with. Tuning is helpful, but not needed. 512MB with good local disk can rebuild. Takes a while. The absolute = minimum for ZFS. 1GB smallest with modern tripped down GUI. ZFS possible with tuning and = works well on small data sets 2GB decent performance with modern GUI so long as you don=E2=80=99t over = do it. ZFS works w/o tuning, but works better with tuning. 4GB decent performance GUI. ZFS no brainer. The low end embedded gear still matters for RAM, but with the latest = rounds of armv6 hardware it matters less. In the mips (32-bit) space = memory still matters a lot, and the above list is partially the result = of listening in on people deploying it. I=E2=80=99d recommend the addition of one sentence: Specialized FreeBSD systems can run in as little as 128MB RAM. which keeps it short enough to make it easy to read, but is specific = enough to not shut the door for other deploys that people might be = considering. I know that=E2=80=99s 4x bigger than the absolute smallest = system, but that=E2=80=99s really about the spot where the current = system starts to become hard to push smaller. It will be a good cutoff = through 11.x to give system integrators guidance that keeps our options = open. The rest looks good as is. So while RAM is cheap in the desktop and server market, it is still a = significant BoM cost in embedded deployments where you ship out hundreds = or thousands of boxes.
