The sysvinit script does this:

  check_privsep_dir() {
      # Create the PrivSep empty dir if necessary
      if [ ! -d /var/run/sshd ]; then
          mkdir /var/run/sshd
          chmod 0755 /var/run/sshd
      fi
  }
  [...]
  case "$1" in
    start)
          check_for_upstart 1
          check_privsep_dir

So does the Upstart job:

  pre-start script
      test -x /usr/sbin/sshd || { stop; exit 0; }
      test -e /etc/ssh/sshd_not_to_be_run && { stop; exit 0; }
  
      mkdir -p -m0755 /var/run/sshd
  end script

And for systemd this should be handled by a tmpfiles.d script:

  d /var/run/sshd 0755 root root

So it's not sufficient to simply state that we need to handle this,
because as far as I can see we already do.  Could you please investigate
why the respective handling for whatever init system you have as pid 1
is not working for you?  Please then take this to a separate bug report,
as this is not at all the same issue as the original one filed as
#645788, and it is not usually good to conflate multiple issues into a
single bug report.

Thanks,
