[pkg-ntp-maintainers] Bug#863857: $PIDFILE unset, so writes to a file called /-g

[積丹尼 Dan Jacobson]

Package: ntp
Version: 1:4.2.8p10+dfsg-3+exp2
Severity: important
File: /usr/lib/ntp/ntp-systemd-wrapper

Because $PIDFILE is never set, you end up writing the PIDFILE to a file
called "/-g" in the root file system.

By the way stopping the deamon does not remove the PIDFILE either,
thus your next version should clean the stray /-g file off the users'
systems lest it be left there forever.
