That's interesting. On my powerbook, I had to comment out the sysctl -w
kern.sysv.shmmax line in /etc/rc. It appears that you can shrink shmmax
but not expand it. This meant that it would properly set it based on
/etc/syscttl.conf, but that (large) setting would then be over-written
by the subsiquent sysctl -w.
