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