it is not uncommon to have /var on a own partition

in theory more security
imagine a root-exploit changing a system binary
much more difficult if the rootfs is readonly
Extra security is certainly a plus. My main reason for wanting to run a
read-only root it to avoid wearing out the consumer grade compact flash
card that I'm using as my root device (yes, I'm cheap).
