# Add these lines to /etc/rc.conf.local or /etc/rc.conf
# to enable this service:
#
# iked_enable (bool):	Set to NO by default.
#			Set it to YES to enable iked.
# iked_ramdisk (bool):	Set to NO by default. See below.
#
# When iked_ramdisk is set to YES, the rc.d script will make sure
# all directories exist, but will not generate a key pair if none
# exists.  The daemon is not started when the key pair no config
# files are missing.  It is assumed the ramdisk is not populated
# completely.  When iked_ramdisk is NO, key pairs are created as
# needed and thr daemon is started unconditionally.
