Bug#738801: cups: /etc/init.d/cups stop/start hang when systemd is installed

[Nye Liu <nyet@mrv.com>]

Package: cups
Version: 1.7.1-4
Severity: important

Dear Maintainer,

   * What led up to the situation?

running /etc/init.d/cups stop or start (for example, as root, or by
logrotate)

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

with cups running:
# /etc/init.d/cups stop
with cups not running:
# /etc/init.d/cups start

   * What was the outcome of this action?

# /etc/init.d/cups stop
[....] Stopping cups (via systemctl): cups.service

hangs indefinitely

If I kill it by hand, then
# /etc/init.d/cups start
[....] Starting cups (via systemctl): cups.service

hangs indefinitely

   * What outcome did you expect instead?

The cups daemon should start/stop as expected.

Also, "systemctl start/stop cups.service" acts the same.
