The problem is if you do it this way, it's not "spin during boot only" media. It will spin up whenever you need to load a new app or utility. You've effectively got a less efficient read-only HD which defeats the purpose of reliability... What you can do instead is to use MFS which is a memory filing system - the kernel either contains the complete MFS image or you can copy part of the image after initial boot, into the MFS slice. You use a minimal FreeBSD system which only has the functionality you need. It can be done in less than 1.5Mb (eg PicoBSD) but to be more comfortable you'd probably be looking at about 5Mb.
