Title:
  229-4ubuntu18: '+' command prefix does not work in ExecStart*= and
  ExecStop*=

Status in systemd package in Ubuntu:
  New

Bug description:
  The systemd version 229-4ubuntu18 from xenial-proposed archive has a
  bug. The '+' prefix (see
  https://www.freedesktop.org/software/systemd/man/systemd.service.html)
  in ExecStart*= and ExecStop*= statements does not work any longer.

  File /lib/systemd/system/systemd-resolved.service.d/resolvconf.conf of
  this version contains two commands prefixed with '+':

  # When resolved is in use, it must be brought up before we consider networking
  # available because otherwise there is a window where DNS resolution doesn't
  # work.
  [Unit]
  Before=network-online.target

  # tell resolvconf about resolved's builtin DNS server, so that DNS servers
  # picked up via networkd are respected when using resolvconf, and that software
  # like Chrome that does not do NSS (libnss-resolve) still gets proper DNS
  # resolution
  [Service]
  ExecStartPost=+/bin/sh -c '[ ! -e /run/resolvconf/enable-updates ] || echo "nameserver 127.0.0.53" | /sbin/resolvconf -a systemd-resolved'
  ExecStopPost=+/bin/sh -c '[ ! -e /run/resolvconf/enable-updates ] || /sbin/resolvconf -d systemd-resolved'

  Those two statements in section [Service] lead to the following two
  error messages in dmesg:

  [    3.687475] systemd[1]: [/lib/systemd/system/systemd-resolved.service.d/resolvconf.conf:12] Executable path is not absolute, ignoring: +/bin/sh -c '[ ! -e /run/resolvconf/enable-updates ] || echo "nameserver 127.0.0.53" | /sbin/resolvconf -a systemd-resolved'
