Bug#212117: ssh: init stop/restart action should use --retry

[<herbert@gondor.apana.org.au>]

Package: ssh
Version: 1:3.6.1p2-3
Severity: normal

On one of my slower machines I lost sshd completely after upgrading
to the latest security update (the unstable version has the same bug
as well).  The reason is that the init script tried to start before
the old sshd is completely stopped:

Sep 22 05:03:56 host sshd[18705]: Received signal 15; terminating.
Sep 22 05:03:58 host sshd[1759]: error: Bind to port 22 on 0.0.0.0 failed: Address already in use.
Sep 22 05:04:16 host sshd[1759]: fatal: Cannot bind any address.

This is probably because the 2-second delay in the init script is
not sufficient.

Rather than extending the delay, please call start-stop-daemon --stop
with --retry so that it does not return until the daemon is truly dead.

Thanks,
