I mentioned this in an earlier thread, but it should be possible to eliminate 
the need to run from memory in all but net boot situations. Either a 
file-backed root can be mounted, with the sections that need to be writeable 
mounted from a memory-backed fs, of the whole filesystem can be overlayed with 
a memory-backed union mount. Either way, only the things that changed would 
require ram. As far as performance degredation goes, FreeBSD has excellent 
filesystem cacheing. Unless a system is pressed for RAM, most of the 
filesystem would wind up resident in the RAM cache anyway.
