So, s-s-d --exec *without* --pidfile is a bit unsafe, as according to the man
page it will kill *all* processes matching /proc/pid/exe (see also guillem's
comments in #593201)

Going further with the dbus idea, we could use something like this

if [ -f /var/run/dbus/system_bus_socket ] ; then
  pid=$(dbus-send --system --dest=org.freedesktop.DBus --print-reply \
   /org/freedesktop/DBus org.freedesktop.DBus.GetConnectionUnixProcessID \
   string:'org.freedesktop.UDisks' 2>/dev/null | grep uint32 | awk '{print $2}')

  [ -n "$pid" ] && kill $pid / restart etc.
fi

Does anyone see any obvious downsides with this approach or thinks this is not a
good idea?

Michael
