Please do not apply that ExecStop= thing. You really shouldn't block
that. Think about people who boot their system with "emergency" on the
kernel cmdline, and thus get a PID 1 plus a shell and nothing else, they
should be able to start dbus and stop it as they wish...

If at all, use RefuseManualStop=yes on the unit, but I don't like that
much either. It's mostly relevant for things like audit where the kernel
might stop if the service is shut down.

The best way is to fix the few services that really need dbus
unconditionally to be around to add After=dbus.service. And all is good.

Title:
  remote file systems hang on shutdown, D-BUS stops too early

Status in D-Bus:
  Confirmed
Status in dbus package in Ubuntu:
  Fix Released

Bug description:
  (part of bug 1431774). During shutdown, D-Bus stops too early. In
  particular, it stops before NetworkManager and remote-fs.target,  so
  that any network unmount  will cause errors and hang the boot. This
  can be seen with

  $ journalctl -b -1 | egrep 'Stop.*(D-Bus|Network M|Remote F)'

  A quick workaround is to add After=dbus.service to
  /lib/systemd/system/NetworkManager.service's [Unit] section, but this
  should be fixed in a more general fashion.
