systemctl preset-all [OPTIONS]

systemctl preset-all resets the enablement state of all installed unit files to the defaults defined in preset policy files. This applies distribution default settings to every unit on the system.
This is typically run once after initial system installation or when resetting to distribution defaults.

full (default), enable-only, or disable-only

Suppress output, return only exit code

Operate on user units

This is a system-wide operation that can change many service enablement states. Use `--preset-mode` to limit to only enabling or disabling. Backup your current configuration before running.

The preset-all subcommand provides a way to reset the entire system to distribution-default service configuration, useful for recovery or standardization.
