Yup
  % ldd /usr/sbin/sshd | grep syst
          libsystemd.so.0 => /lib64/libsystemd.so.0 (0x00007f0e5b715000)

Simple seems to have fixed it.  I was also trying with "forking" as
the
type and that was failing as well.

Thanks.

That is not as simple as that -- we lived with "simple" for long time,
but it was not covering some corner cases so we ended up using the
sd_notify, since that was the only reliable way for systemd to know the
service is working.

For others interested in this topic, there was a long discussion in bug
#2641, unfortunately without upstream solution:
