One thing I've done when booting minimal-memory systems (such as an HP 9000-332 with 8MB) is put attaching a swap file at the very top of /etc/rc, because I was seeing the attempt to execute rc failing due to lack of memory. Normally swap is attached towards the middle or end of /etc/rc, from what I recall anyway.
