i don't think there's an out-of-the-box solution. have you checked out ports to
see if there's something there which might do what you're looking for?
another possibility would be to use tmpfs and store the files and libraries
on a memory based partition. you could write a script which would copy
files/libs to the tmpfs partition during boot time e.g.
