==============

i don't know if linux is caching it. if it is, then freebsd should at 
least have an option to do the same. the real test will be trying linux on 
the freebsd hardware and freebsd on the linux hardware. i don't know when 
i'll get a chance to do it, but i'll update the list with details when it 
happens.
