The release of the service manager s6-rc 0.7.0.0 has been published, designed to manage the execution of initialization scripts and services. It supports tracking dependency trees and automatically starting or stopping services to reach the specified state. The s6-rc toolkit can be used in both initialization systems and for organizing the startup of arbitrary services tied to events reflecting changes in system state. The system supports initialization scripts compatible with sysv-init and can import dependency information from sysv-rc or OpenRC. The code is written in C and is distributed under the ISC license. <\/p>\n

The s6-rc service manager includes a set of utilities for starting and stopping long-running processes (daemons) or scripts that terminate immediately upon initialization. It ensures the parallel launch of independent services and guarantees a consistent sequence of script execution across different launches. All state changes are handled with respect to dependencies; for example, when starting a service, the necessary dependencies for its operation are automatically launched, and when stopping, dependent services are also halted. <\/p>\n

Unlike other service managers, s6-rc supports proactive (in offline mode) construction of a dependency graph for the existing set of services, allowing resource-intensive dependency analysis to be completed separately, rather than during boot or state change. The system is not monolithic and is divided into a series of separate and replaceable modules, each of which, in accordance with Unix philosophy, addresses only a specific task. The s6-rc project adheres to minimalism (it contains nothing superfluous) and consumes minimal resources. <\/p>\n

Instead of runlevels in s6-rc, the concept of bundles is proposed, allowing services to be grouped by arbitrary criteria and tasks. To enhance efficiency, a compiled dependency database is created by the s6-rc-compile utility based on the contents of directories with service start\/stop files. Utilities s6-rc-db and s6-rc-update are provided for parsing and manipulating the database. The s6 toolkit is used in Obarun, Adelie, and Artix distributions, and can optionally be used in Gentoo, Void, and Alpine. <\/p>\n

The project also develops companion packages that complement s6-rc: <\/p>\n
