            Bug ID: 190643
           Summary: /usr/sbin/daemon -P option does not work as documented
           Product: Base System
           Version: 9.2-STABLE
          Hardware: Any
                OS: Any
            Status: Needs Triage
          Severity: Affects Some People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: barney at databus.com

If daemon's -P option is used without the -p option, the pidfile is not removed
when the process terminates.  To demonstrate:
/usr/sbin/daemon -P pid.daemon sleep 5
After sleep terminates, pid.daemon is left around, pointing to a nonexistent
process.  It also seems that there is no separate daemon process, as the
pid.daemon file points to the sleep process.

The danger of leaving the pidfile around is of course when pids cycle around an
unintended process might be terminated.

This might be treated as a documentation bug, as using -P without -p or -r is
at least unusual.
