The file
|
||
|
|
.B /etc/system.conf
|
||
|
|
is the global system configuration file that contains the
|
||
|
|
configuration for all the primary system services. This is the file
|
||
|
|
that the \fBservice\fR utility uses by default. Custom configuration
|
||
|
|
files with the same format can be specified on a per-service basis. See
|
||
|
|
.BR service (8)
|
||
|
|
for more details.
|
||
|
|
|
||
|
|
This page is a summary of all the elements that can be found in this
|
||
|
|
configuration file.
|
||
|
|
.PP
|
||
|
|
The syntax used is that of the common configuration file described in
|
||
|
|
.BR configfile (5).
|
||
|
|
.PP
|
||
|
|
The \fBservice\fR utility scans the configuration file from beginning to end
|
||
|
|
to gather information about a specific system service when starting or
|
||
|
|
updating the properties of a service.
|
||
|
|
The file contains a collection of service entries of the form:
|
||
|
|
|
||
|
|
.nf
|
||
|
|
\fBservice\fR \fI<program_name>\fR
|
||
|
|
\fB{\fR
|
||
|
|
\fI[option 1]\fR
|
||
|
|
\fI[option 2]\fR
|
||
|
|
...
|
||
|
|
\fI[option N]\fR
|
||
|
|
\fB};\fR
|
||
|
|
.fi
|
||
|
|
.PP
|
||
|
|
where \fI<program_name>\fR is the name of the program used to start the
|
||
|
|
given system service. In each service entry, the following options can
|
||
|
|
be used:
|
||
|
|
.PP
|
||
|
|
\fBuid\fR \fI<uid|user name>\fR\fB;\fR
|
||
|
|
.PP
|
||
|
|
.RS
|
||
|
|
specifies the user id or the user name to use to run the system service.
|
||
|
|
Many system services run with root privileges (uid \fB0\fR).
|
||
|
|
The default user is service (uid \fB12\fR).

.PP

specifies the list of ipc targets (processes and kernel) the system service can
|
||
|
|
talk to. \fIALL\fR allows all the possible targets, \fIALL_SYS\fR is similar but
|
||
|
|
excludes user processes. When an explicit list is given, each target
|
||
|
|
must be identified by its label (assigned to the corresponding system service).
|
||
|
|
Exceptions are user processes (use pseudo-label \fIUSER\fR) and
|
||
|
|
the kernel for kernel calls (use pseudo-label \fISYSTEM\fR). The default is
|
||
|
|
\fIALL_SYS\fR.

\fIALL\fR allows all the kernel calls, \fIBASIC\fR only allows basic kernel

calls (see macro \fBSYS_BASIC_CALLS\fR in \fB<minix/com.h>\fR),
|

\fINONE\fR allows no kernel call. This option only makes sense if the
|
||
|
|
option \fBipc\fR includes the kernel as a valid target.
|

The default is \fIBASIC\fR.

\fIALL\fR allows all the possible I/O ranges, \fINONE\fR allows no I/O range
|
||
|
|
at all. When an explicit list is given, each range is identified by a base
|
||
|
|
address and an optional length. When no length is given, length \fB1\fR is
|

assumed. The default is \fINONE\fR.

specifies the signal manager the system service is assigned to. The signal
|

|
manager intercepts all the termination and non-termination signals
|
||
|
|
(including signal generated by runtime exceptions, e.g. SIGSEGV) on behalf
|
||
|
|
of the service and reacts accordingly. \fISELF\fR allows the service to
|
||
|
|
become its own signal manager. This option should be used with care,
|
||
|
|
since a lethal signal for the service will immediately trigger a
|
||
|
|
kernel panic. A separate system service that acts as the designated signal
|
||
|
|
manager must be specified using its label. The default is specified in
|

\fB<minix/priv.h>\fR (see macro \fBDSRV_SM\fR).

the service to be scheduled directly by the kernel. A separate system
|

service that acts as the designated scheduler must be specified
|
