 Causes a file (by default, \fB\*(PN.pid\fR) to be created indicating
-the PID of the running process.  If \fIpidfile\fR is not specified, or

-\fB-f\fR, \fB--force\fR
-By default, when \fB-P\fR or \fB--pidfile\fR is specified and the

+\fB\-\-monitor\fR
+Creates an additional process to monitor the \fB\*(PN\fR daemon.  If
+the daemon dies due to a signal that indicates a programming error
+(\fBSIGABRT\fR, \fBSIGALRM\fR, \fBSIGBUS\fR, \fBSIGFPE\fR,

+the daemon dies or exits for another reason, the monitor process exits.
+.IP
+This option is normally used with \fB\-\-detach\fR, but it also
+functions without it.
+.
+.TP
+\fB\-\-no\-chdir\fR
+By default, when \fB\-\-detach\fR is specified, \fB\*(PN\fR 
+changes its current working directory to the root directory after it 
+detaches.  Otherwise, invoking \fB\*(PN\fR from a carelessly chosen 
+directory would prevent the administrator from unmounting the file 
+system that holds that directory.
+.IP
+Specifying \fB\-\-no\-chdir\fR suppresses this behavior, preventing
+\fB\*(PN\fR from changing its current working directory.  This may be 
+useful for collecting core files, since it is common behavior to write 
+core dumps into the current working directory and the root directory 
+is not a good directory to use.

+This option has no effect when \fB\-\-detach\fR is not specified.
