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>Kill mode</header>

<p>Controls how systemd terminates processes belonging to the service. This
|
|
writes <tt>KillMode=</tt>.</p>
|
|
<p><tt>control-group</tt> is the default and safest choice: systemd stops the
|
|
main process and any remaining child processes in the service cgroup.
|
|
<tt>mixed</tt> sends the first termination signal only to the main process,
|
|
then later kills remaining cgroup processes if needed.</p>
|
|
<p><tt>process</tt> stops only the main process and can leave child processes
|
|
behind. <tt>none</tt> makes systemd run the stop command but not kill service
|
|
processes. Avoid <tt>process</tt> and <tt>none</tt> unless you know the
|
|
application manages its own process tree safely.</p>
