Another FreeBSD daemon manager not running

Plone Support Administering Plone sites
1

OS: FreeBSD11.2-p3

I executed the 5.1 installer as root using
--target=/usr/local/plone standalone

added these eggs to /usr/local/plone/zinstance/buildout.cfg before executing sudo -u plone_buildout bin/buildout

plonetheme.cleanblog
plone.app.linkintegrity
plonetheme.future_imperfect
plone.app.dexterity
redturtle.drawio

I do this:
root@freebsd:/usr/local/plone/zinstance # bin/plonectl start
instance: . . . . . . . . . . .
daemon manager not running

From what I could see there should be a socket called zdsock created somewhere, but I couldn't figure out where. zope itself seems to have no trouble creating a UNIX socket.

The server seems to run fine, I have connected to it and created a site, but it cannot be shutdown due to this without sending a kill signal.

The var/log/instance.log has no adverse messages.
I couldn't find any log information from zdaemon.

I suspect zdaemon is trying the create the socket outside this tree, failing and not making any noise.

This is as far as I could take it. Any help is most appreciated as I'm writing up the installation procedure for the FreeBSD forum and this is stopping me from completing that.

Thanks in advance for any thoughts -- lee
