The actual init script of ircd-hybrid looks really old fashioned, it needs a rewrite to be compatible with the rc.d system.
The following file is a new init script that is using the rc.d facilities.
--- cut here --- file: /usr/ports/irc/ircd-hybrid/files/ircd-hybrid.sh
# PROVIDE: ircd-hybrid
# REQUIRE: DAEMON
# BEFORE: LOGIN
# KEYWORD: FreeBSD shutdown
# To get ircd-hybrid enabled at boot, add the following lines to /etc/rc.conf :
# ircd_hybrid_enable (bool): Set to "NO" by default.
# Set it to "YES" to enable ircd-hybrid.
[ -z "$ircd_hybrid_enable" ] && ircd_hybrid_enable=NO
[ -z "$ircd_hybrid_user" ] && ircd_hybrid_user=ircd
chown $ircd_hybrid_user $pidfile
--- cut here ---
How-To-Repeat: Just look into /usr/ports/irc/ircd-hybrid/files/ircd-hybrid.sh
