他只是系統 per-process limit 的限制。
<quote from /usr/src/sys/conf/NOTES>
# FreeBSD processes are subject to certain limits to their consumption
# of system resources. See getrlimit(2) for more details. Each
# resource limit has two values, a "soft" limit and a "hard" limit.
# The soft limits can be modified during normal system operation, but
# the hard limits are set at boot time. Their default values are
# in sys/<arch>/include/vmparam.h. There are two ways to change them:
#
# 1. Set the values at kernel build time. The options below are one
# way to allow that limit to grow to 1GB. They can be increased
# further by changing the parameters:
#
# 2. In /boot/loader.conf, set the tunables kern.maxswzone,
# kern.maxbcache, kern.maxtsiz, kern.dfldsiz, kern.maxdsiz,
# kern.dflssiz, kern.maxssiz and kern.sgrowsiz.
#
# The options in /boot/loader.conf override anything in the kernel
# configuration file. See the function init_param1 in
# sys/kern/subr_param.c for more details.

好像 init_param1() 的東東是不屬 sysctl 管的。可以由 ulimit -a
得知。
ps.像我編字型，一個 Unicode 字型那麼大，使用 fontforge，不把 maxdsiz
增加，根本就沒辦法用。
