    - d/samba-common.dhcp: If systemctl is available, use it to query the
      status of the smbd service before trying to reload it. Otherwise,
      keep the same check as before and reload the service based on the
      existence of the initscript. (LP #1579597)
      [In Debian since 2:4.7.4+dfsg-2]
    - debian/patches/passdb_dont_return_ok_if_pinfo_not_filled.patch:
