I am pretty sure many readers are interested in how to run such "boxes" that can be used as highperf firewalls/routers or NIDS. This implies that a lightened file directory burnt on a media (CD-ROM) is loaded in memory at boot time. Which filesystems are available then to store files in a RAM disk ? swapfs ? But then how can one prevent this extra "swapfs" from being used for its usual purpose ... swap so that it is reserved for file storage at user-level ? I may be mixing things a bit as i don't know about kernel internals (is there a "freebsd kernel design guide" available on-line ?), but i would be pleased to get an answer.
