Where does Solaris start sshd?

Question

I'm working on a Solaris 11.3 i86pc machine. Solaris ships an ancient version of OpenSSH and SunSSH, and they can only use RSA. I am trying to update OpenSSH.

I built and installed a modern version in /opt/ssh. I'm now trying to tell Solaris to use it. The problem is, I have not found where Solaris starts the OpenSSH daemon. I expect there's a config file or script that calls sshd but I have not been able to locate it.

Where does Solaris start the sshd daemon?

---

It does not appear to be started from a rc.* file (per Startup script not executing after reboot on Solaris):

# /usr/gnu/bin/grep -IR sshd /etc/rc*
#

And I can't get my grep of /etc to complete:

# /usr/gnu/bin/grep -IR --exclude-dir=dev sshd /etc
/etc/ssh/sshd_config:# Configuration file for sshd(1m) (see also sshd_config(4))
/etc/ssh/sshd_config:# This file is used for the SunSSH and the OpenSSH versions of the sshd(1m)
...
/etc/ssh/sshd_config:# Are root logins permitted using sshd.
/etc/ssh/sshd_config:# Note that sshd uses pam_authenticate(3PAM) so the root (or any other) user

Solaris 10 and later use the Service Management Facility (SMF) to start daemons. SSH is normally started by the SMF service named svc:/network/ssh:default.

Startup scripts are specified in the SMF manifest for each service - you can see what command the ssh service runs with:

# svcprop -p  start/exec svc:/network/ssh:default
/lib/svc/method/sshd\ start
