NAME

minisvc - daemontools mini Service Configuration Tool

SYNOPSYS

minisvc [ options ]

DESCRIPTION

minisvc is a shell frontend for configuring supervise(8) services under svscan(8). For every service created, it also creates a supervised log service, that uses multilog(8), in /var/log/svc direcotry. You can install svscan(8) to be started by the system using the command

minisvc --config=add-boot.

Similarly, you can remove svscan(8) from startup by using the command

minisvc --config=rm-boot.

minisvc offers tiny subset of indimail-mta's svctool(8) config tool features.

svctool can be used to dump the entire configuration of indimail on stdou.

minisvc --servicedir=/service --dumpconfig --cntrldir=/etc/indimail/control

minisvc requires root privilege to run.

Services & Environment variables

svctool primary function is for creating supervised services in /service. You can change the location of the service directory by specifying --servicedir option.

When you create any service, svctool stores the entire command line invocation wth arguments in /service/name/variables/.options. This allows svctool to recreate entire configuration for a service when you use the --refreshsvc option. Using envdir(8), supervise(8) services can be run with set of environment variables or a set of variables removed from the environment. The environment variables are those needed by applications run by supervise(8). These environment variables are stored as files in /service/name/variables directory. svctool can store all environment variables set for a service in /service/name/variables/.variables. This file can be created by running the command

svctool --servicedir=/service --save-variables --force

Once you have saved all environment variables as key=value lines in a file, svctool can restore all environment variables to original state by running the command

svctool --servicedir=/service --restore-all-variables --force

name refers to a supervised service name. See svscan(8), supervise(8).
