This PR adds a standalone Systemd Services and Units module for managing systemd units across system and user scopes. The module keeps systemd-specific behavior separate from the legacy Bootup and Shutdown module and is implemented as standalone `strict`/`warnings` Perl code rather than depending on its existing init helpers. Those helpers intentionally smooth over multiple init systems, while this module keeps systemd-specific file handling, user-manager behavior, ACL checks, and control operations explicit, scoped, and easier to audit. It includes: - Tabbed views for services, timers, sockets, paths, targets, storage, resources, devices, and user units - Guided creation and editing for common unit types, with contextual fields, validation, and help - User-scoped unit management with linger support and safe handling of home-directory unit files - Runtime actions for start, stop, restart, enable, disable, status, logs, properties, dependencies, and system-unit mask/unmask - Drop-in override inventory plus create, edit, and delete flows - Manual unit-file editing with daemon reload reminders and actions - Configurable module behavior, visible tabs, display options, and post-create navigation - Comprehensive ACL controls for system/user scopes, actions, manual edits, drop-ins, linger, reload, backup, and user filters - Safe Webmin user support through a scoped safe ACL preset - Virtualmin integration for granting domain owners access to their own systemd user units - Tests for unit generation, safety checks, ACL behavior, user-unit handling, backup coverage, and Perl::Critic compatibility A companion Virtualmin PR adds template integration so domain owners can be granted scoped access to their own systemd user units when this module is installed.

<header>Introduction</header>
|
|
<p>This module manages units controlled by systemd, including services, timers,
|
|
sockets, paths, targets, storage units, resource-control units, devices and user
|
|
units. The index groups units by type and shows both the unit file state, such
|
|
as enabled, disabled, static or masked, and the runtime state reported by
|
|
systemd.</p>
|
|
<p>Use the unit tables to start, stop, restart, enable, disable, mask, inspect
|
|
status or read logs. Existing units can be edited directly when their unit files
|
|
are writable, or customized with drop-in override files when packaged base units
|
|
should be left intact. User units are managed through the owning user's systemd
|
|
manager, with linger controls for units that should keep running without an
|
|
active login.</p>
