Short answer yes - the sysctl should be updated in /etc/sysctl.conf. There was backwards compatibility support for the old name but it was removed recently with an OpenZFS update. Unfortunately bsdinstall was also writing the old name into /etc/sysctl.conf until just now. We have some worth to do prior to 15.0 to address this situation.
