Example: nfsserver should have # Required-Start: $portmap # Also, required services are started before the dependent ones. # The runlevel editor will warn about such missing hard dependencies # and suggest enabling. During system startup, you may expect an error, # if the dependency is not fulfilled. # (b) Specifying the init script ordering, not real (hard) dependencies. # This is needed by insserv to determine which service should be # started first (and at a later stage what services can be started # in parallel). The tag Should-Start: is used for this. # It tells, that if a service is available, it should be started # before. If not, never mind. # * When specifying hard dependencies or ordering requirements, you can # use names of services (contents of their Provides: section) # or pseudo names starting with a $. The following ones are available # according to LSB (1.1): # $local_fs all local file systems are mounted # (most services should need this!) # $remote_fs all remote file systems are mounted # (note that /usr may be remote, so # many services should Require this!) # $syslog system logging facility up # $network low level networking (eth card, ...) # $named hostname resolution available # $netdaemons all network daemons are running # The $netdaemons pseudo service has been removed in LSB 1.2. # For now, we still offer it for backward compatibility. # These are new (LSB 1.2): # $time the system time has been set correctly # $portmap SunRPC portmapping service available # UnitedLinux/SUSE/Novell extensions: # $ALL indicates that a script should be inserted # at the end # * The services specified in the stop tags # (Required-Stop/Should-Stop) # specify which services need to be still running when this service # is shut down. Often the entries there are just copies or a subset # from the respective start tag. # * Should-Start/Stop are now part of LSB as of 2.0, # formerly SUSE/Unitedlinux used X-UnitedLinux-Should-Start/-Stop. # insserv does support both variants. # * X-UnitedLinux-Default-Enabled: yes/no is used at installation time # (%fillup_and_insserv macro in %post of many RPMs) to specify whether # a startup script should default to be enabled after installation. # # Note on runlevels: # 0 - halt/poweroff 6 - reboot # 1 - single user 2 - multiuser without network exported # 3 - multiuser w/ network (text mode) 5 - multiuser w/ network and X11 (xdm) # # Note on script names: # http://www.linuxbase.org/spec/refspecs/LSB_1.3.0/gLSB/gLSB/scrptnames.html # A registry has been set up to manage the init script namespace. # http://www.lanana.org/ # Please use the names already registered or register one or use a # vendor prefix. # Init script default settings BB_CONF="/etc/boxbackup/bbackupd.conf" BB_PROG="/usr/local/sbin/bbackupd" BB_PIDFILE="/var/lib/bbackupd/bbackupd.pid" BBC_PROG="/usr/local/sbin/bbackupctl" # Check for missing binaries (stale symlinks should not happen) # Note: Special treatment of stop for LSB conformance bb_BIN=$BB_PROG test -x $bb_BIN || { echo "$bb_BIN not installed"; if [ "$1" = "stop" ]; then exit 0; else exit 5; fi; } test -x $BBC_PROG || { echo "$BBC_PROG not installed"; if [ "$1" = "stop" ]; then exit 0; else exit 5; fi; } # Check for existence of needed config file and read it test -r $BB_CONF || { echo "$BB_CONF not existing"; if [ "$1" = "stop" ]; then exit 0; else exit 6; fi; } # Source LSB init functions # providing start_daemon, killproc, pidofproc, # log_success_msg, log_failure_msg and log_warning_msg. # This is currently not used by UnitedLinux based distributions and # not needed for init scripts for UnitedLinux only.
