It is -now possible to write a modularised set of boot scripts without the -complex and fragile numbered symlink scheme used in SysV-style boot -scripts. Each script can simply declare, using \fBneed\fP(8), what -must run before them. -.SH DESCRIPTION for need -The \fBneed\fP programme is a utility that tells \fBsimpleinit\fP(8) -to start a \fIservice\fP (usually a script in \fI/sbin/init.d\fP) and -will wait for the service to become available. If the service is -already available, it will not be started again. - -The \fB-r\fP option is used to tell \fBsimpleinit\fP(8) to "roll back" -(stop) services up to (but not including) \fIservice\fP. If -\fIservice\fP is not specified, all services are stopped. The \fB-r\fP -option thus allows the system to be partially or wholly shut down in -an orderly fashion. The \fBshutdown\fP(8) programme still needs to be -run. - -.SH DESCRIPTION for display-services -When invoked as \fBdisplay-services\fP it will write the list of -currently available services and the list of failed services to the -standard output. - -.SH DESCRIPTION for provide -When invoked as \fBprovide\fP it tells \fBsimpleinit\fP(8) that the -parent (calling) process will be providing a service with name -\fIservice\fP. If the calling process exits successfully (status 0) -the service is deemed to be available. Only one instance of -\fIservice\fP may be started, so alternate providers will block and -may fail. - -Using \fBprovide\fP it is possible to have multiple potential -providers for the same (generic) service (e.g. \fBsendmail\fP and -\fBqmail\fP both provide a \fBmta\fP service), where only one actually -provides the service. This may be used by service startup scripts -which check for configuration files. -.SH EXIT CODE -The exit code from \fBneed\fP is 0 if the service was successfully -started, 1 if the service failed badly, and 2 if the service is -unavailable (i.e. disabled in configuration files). These exit codes -reflect the exit codes from the service startup scripts. - -The exit code from \fBneed -r\fP is 0 if the service was successfully -stopped, 1 if the service could not be stopped, and 2 if the service -was not available to start with. The service shutdown scripts may only -return 0 (for success) or 1 (for failure). - -The exit code from \fBprovide\fP is 0 if the service may be provided, -1 if it may not, and 2 if the parent process is not a child of -init. It may block waiting for another provider which is initialising -the service. -.SH SIGNALS -\fBinitctl\fP(8) uses \fBSIGUSR1\fP, \fBSIGUSR2\fP and \fBSIGPOLL\fP -for communication with \fBsimpleinit\fP(8). Don't send these signals -to it. -.SH FILES -.PD 0 -.TP 20 -.BI /dev/initctl -This is the control FIFO, created by \fBsimpleinit\fP(8), which -\fBinitctl\fP(8) writes commands to. -.SH SEE ALSO -.BR simpleinit (8), -.BR init (8) -.PP -A more complete discussion of the new boot script system, based on -\fBneed\fP(8), is available from: -http://www.atnf.csiro.au/~rgooch/linux/boot-scripts/ -.SH AUTHOR -Richard Gooch (rgooch@atnf.csiro.au) - -.SH AVAILABILITY -The initctl command is part of the util-linux package and is available from -ftp://ftp.kernel.org/pub/linux/utils/util-linux/. |
