Config - System Configuration Dispatcher

Overview

The config command is a unified dispatcher for system configuration tasks. It replaces scattered toggle-*, setup-*, and config-* commands with a single interface.

Key Concept: All configuration targets support consistent actions: enable, disable, status, and help.

Quick Reference

Category	Targets
Services	docker, cockpit, syncthing, libvirtd, sshd
Desktop	gamemode, steam-autostart
Security	passwordless-sudo
Apps	podman-permissions, podman-extensions, winboat
Development	gpu, dev-environment

Parameters

Command Pattern

ujust config TARGET="" ACTION="" ARGS...

Parameter	Values	Description
TARGET	See targets below	Configuration target
ACTION	enable, disable, status, help	Action to perform
ARGS	varies	Additional arguments

Without TARGET, shows interactive picker.

Service Targets

Docker

ujust config docker status        # Show Docker service status
ujust config docker enable        # Enable Docker daemon
ujust config docker disable       # Disable Docker daemon
ujust config docker enable-socket # Enable socket activation only

Cockpit

ujust config cockpit status       # Show Cockpit status
ujust config cockpit enable       # Enable web console
ujust config cockpit disable      # Disable web console

Access at: [https://localhost](https://localhost):9090

Syncthing

ujust config syncthing status     # Show Syncthing status
ujust config syncthing enable     # Enable file sync
ujust config syncthing disable    # Disable file sync

Libvirtd

ujust config libvirtd status      # Show libvirt status
ujust config libvirtd enable      # Enable virtualization
ujust config libvirtd disable     # Disable virtualization

SSH Server

ujust config sshd status          # Show SSH server status
ujust config sshd enable          # Enable SSH server
ujust config sshd disable         # Disable SSH server

Desktop Targets

Gamemode

ujust config gamemode status      # Show current session type
ujust config gamemode gamemode    # Set to Game Mode session
ujust config gamemode desktop     # Set to Desktop session

Steam Autostart

ujust config steam-autostart status   # Show autostart status
ujust config steam-autostart enable   # Enable Steam autostart
ujust config steam-autostart disable  # Disable Steam autostart

Security Targets

Passwordless Sudo

ujust config passwordless-sudo status   # Show sudo config
ujust config passwordless-sudo enable   # Enable passwordless sudo
ujust config passwordless-sudo disable  # Disable passwordless sudo

Warning: Enabling passwordless sudo reduces security. Useful for development/automation.

Application Targets

Podman Permissions

ujust config podman-permissions status   # Show Podman access
ujust config podman-permissions enable   # Grant Podman Desktop access
ujust config podman-permissions disable  # Revoke access

Podman Extensions

ujust config podman-extensions show      # List installed extensions
ujust config podman-extensions open      # Open extension manager

WinBoat

ujust config winboat launch              # Launch Windows app
ujust config winboat info                # Show WinBoat info

Development Targets

GPU Containers

ujust config gpu status       # Show GPU container support
ujust config gpu setup        # Setup GPU passthrough

Configures:

• NVIDIA Container Toolkit

• AMD ROCm container support

• Intel oneAPI container support

Dev Environment

ujust config dev-environment verify      # Verify dev tools installed

Checks for required development tools and reports missing items.

Common Workflows

Setup Development Environment

# Enable passwordless sudo for automation
ujust config passwordless-sudo enable

# Enable Docker for container development
ujust config docker enable

# Setup GPU container support
ujust config gpu setup

# Verify everything is ready
ujust config dev-environment verify

Enable Remote Access

# Enable SSH server
ujust config sshd enable

# Enable web console (Cockpit)
ujust config cockpit enable

# Check both are running
ujust config sshd status
ujust config cockpit status

Gaming Setup

# Set to Game Mode session
ujust config gamemode gamemode

# Enable Steam autostart
ujust config steam-autostart enable

Return to Desktop

# Set to Desktop session
ujust config gamemode desktop

# Disable Steam autostart
ujust config steam-autostart disable

Non-Interactive Usage

All commands work without TTY:

# CI/automation-friendly
ujust config docker enable
ujust config passwordless-sudo enable

Troubleshooting

Service Won't Start

Symptom: ujust config <service> enable completes but service not running

Fix:

# Check service status
systemctl status <service>

# Check logs
journalctl -u <service> -n 50

# Try manual start
sudo systemctl start <service>

Podman Permissions Not Working

Symptom: Podman Desktop can't access podman

Cause: Flatpak permissions not configured

Fix:

ujust config podman-permissions enable
# Restart Podman Desktop

GPU Containers Not Working

Symptom: Containers can't access GPU

Cause: GPU container toolkit not configured

Fix:

ujust config gpu setup
# May require reboot
