Otherwise when we add support for saving and restoring configuration of internal devices around kernel module unload and reload, there's no easy way for the "restore" code to tell when all the interfaces should be set up and ready for configuration.

\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 the \fIpidfile\fR argument is not
|
|
specified, or
|
|
if it does not begin with \fB/\fR, then it is created in
|
|
\fB@RUNDIR@\fR.
|
|
.IP
|
|
If \fB\-\-pidfile\fR is not specified, no pidfile is created.
|
|
.
|
|
.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.
|
|
.IP
|
|
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. \*(DD
|
|
.
|
|
.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.
