Reviewer's Guide

Adds reusable helper functions for managing rc.conf and safely starting services, and wires them up to automatically enable and start VirtualBox guest services within the xconfig script.

File-Level Changes

Change	Details	Files
Introduce reusable helpers for rc.conf inspection, enabling services, and safe service startup.	Add rc_conf_has function to check whether a given key/value or pattern is present in rc.conf Add enable_rc_conf helper to idempotently append or update service_enable flags in rc.conf Add start_service_safe wrapper to start services only when enabled and handle errors or missing init scripts more gracefully	bin/xconfig
Automate enabling and starting of VirtualBox guest services using the new helpers.	Use enable_rc_conf to ensure vboxguest_enable and vboxservice_enable are set to YES in rc.conf when appropriate Use start_service_safe to start vboxguest and vboxservice after configuration, avoiding duplicate startups and improving error handling Gate VirtualBox setup behind environment or platform checks (e.g., only run on VirtualBox/FreeBSD guests) if such detection logic exists in the script	bin/xconfig
