\fB--pidfile\fR[\fB=\fIpidfile\fR]
|
|
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
|
|
if it does not begin with \fB/\fR, then it is created in
|
|
\fB@RUNDIR@\fR.
|
|
|
|
.TP
|
|
\fB--overwrite-pidfile\fR
|
|
By default, when \fB--pidfile\fR is specified and the specified pidfile
|
|
already exists and is locked by a running process, \fB\*(PN\fR refuses
|
|
to start. Specify \fB--overwrite-pidfile\fR to cause it to instead
|
|
overwrite the pidfile.
|
|
|
|
When \fB--pidfile\fR is not specified, this option has no effect.
|
|
|
|
.TP
|
|
\fB--detach\fR
|
|
Causes \fB\*(PN\fR to detach itself from the foreground session and
|
|
run as a background process.
|
|
|
|
.TP
|
|
\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
|
|
(e.g. \fBSIGSEGV\fR, \fBSIGABRT\fR), then the monitor process starts a
|
|
new copy of it. If the daemon die 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.
|
|
.IP
|
|
This option has no effect when \fB--detach\fR is not specified.
