Why do you need watershed in the first place? With the current package,
the unit gets activated once if the PathExistsGlob triggers, and not re-
triggered while it's running. Once it's done uploading (and thus
systemctl status apport-noui.service gets back to "inactive (dead)", it
will be re-triggered on new events. Isn't that what we want?

What's missing here?

Title:
  using watershed in apport-noui.service causes multiple instances of
  watershed to run

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  I've modified /lib/systemd/system/apport-noui.service to contain the
  following:

  ExecStart=/lib/udev/watershed /usr/share/apport/whoopsie-upload-all

  With the hope that bug 1473562 will be resolved under systemd. (Note
  that using watershed works with upstart and /etc/init/apport-
  noui.conf.)

  I've tested this by setting the PathExistsGlob to
  '/var/crash/*.nothing', then creating a bunch of crash files as in bug
  1473562, switching the PathExistsGlob back to '/var/crash/*.crash' and
  running 'sudo systemcl daemon-reload'.  After this I see the following
  in my journal.

  journalctl --since "4 min ago" /lib/udev/watershed

  ....

  So watershed is called a number of times equal to the number of .crash
  files that exist in /var/crash/.
